[Ho'-lo-sfear] (N): A holosphere is a three-dimensional, spherical holographic
imaging system that engages participants in a virtual three-dimensional
environment. It achieves this through (1) holographic projection
of an image onto a physical, spherical projection surface or (2) the creation
of a virtual sphere using interference patterns from projected coherent-phase
light. A holosphere can reduce the choppiness that occurs where angular
flat surfaces meet, such as with three-dimensional, polygonal imaging systems
like projection cubes. True holospheres are not a commercial reality
at this time, but are expected by the year 2015. Until then,
you can be among the first to point the way with a Holosphere

Thus far, utilization of holographic engineering has been relatively limited and commonly aimed on the regions of design, entertainment and protection. However, the thickness and scope of holographic development products and services is expanding. It is on the edge of speedy progress in several new areas encompassing: files saving and recreation; material investigation; artificial intelligence; media; navigation; medical practice; athletics; schooling; and manufacturing.
Before further discussion of holographic innovation applications, we should evaluate the basics of how holographic likenesses are recorded in, and retrieved from, optical media. In order to record and retrieve a meaningful holographic photo, the converging beam rays must be “coherent.” Coherent rays are ones in which the light undulations are ordered and synchronized. Without coherence, one just gets the three-dimensional equivalent of the “white noise” that shows up on a television that is not tuned to a station. Lasers have coherent light waves and are regularly used for holographic technology. Generally an isolated laser shaft is split through a semi-reflective mirror into the signal ray and reference ray to ensure synchronization of the rays.
To record the illustration of a thing using holographic engineering, the signal ray is shown through an expander lens onto the thing and then reflected off the thing into three-dimensional, photosensitive optical media (such as a crystal or polymer) where it intersects with a reference beam. The resulting interference configuration between the signal and reference beams within the optical media induces chemical reactions that record the holographic illustration in the media. To retrieve the holographic vision, a reference shaft is shown on the hologram-engraved photosensitive material with the same angle and wavelength that was used to mark the original hologram. This causes refraction within the media and recreates the holographic illustration in three dimensions exterior to the media. The holographic image shows up in three dimensions due to observed parallax.
To record data using holographic innovation, a “Spatial Light Modulator” (SLM) encodes a total page of data into the signal shaft that is then projected into the photosensitive optical media. As is the case with engraving holographic visions of items, the signal and reference light beams intersect and sketch the information configuration in the optical media. For data retrieval, the patterns of light and darkness from the recreated image are reconverted into electronic files using a “Detector Array” (DA).
When holographic files will generally just be recorded one-time in optical media, then the media is “Holographic Read-Only-Memory” (HoloROM). When holographic data may be repeatedly accessed and changed in real time, then the media is “Holographic Random-Access-Memory” (HoloRAM).
Holographic information retention and processing systems offer the potential for information read that is much swifter than that of present two-dimensional systems. Two-dimensional information storage systems such as CDs and DVDs record and retrieve information in a serial way -- one bit at a time. Holographic data systems accumulate and retrieve data in parallel, an overall (million-bit) page of data at a time. Different pages may be reached in an instant by using distinct shaft angles and wavelengths. Beam angle and wavelength can be modified much swifter than the mechanical motion demanded to access different sectors in two-dimensional media. Holographic memory is particularly favorable for exploring through immense quantities of information to identify patterns or links among files.
Another reason that holographic information may be recorded and captured more rapidly than twirling magetic media is that laser shafts, without the inertia of mechanical reading and writing mechanisms, will generally be moved very rapidly.
In addition to providing quicker read and bigger density, holographic technology unlocks up revolutionary means of files comparison and recreation. Most present information retention and retrieval systems require fine-tuned specification of data spot in order to retrieve files and they process it in a serial manner. In contrast, holographic technology enables investigating large quantities of information a complete page at a time to assess general patterns and resemblance of meaning. With holographic science, the relative match between a macro search configuration and information pages throughout an optical volume will likely be measured without distinct comparison of unique information elements. This is referred to as “Associative Retrieval.” Associative reconstruction is more tolerant of imprecision and fuzzy logic, and more matching to human cognition, than conventional data retention and recreation systems.
Holographic data memory and reading additionally has the capacity for greater capacity to recover from minor errata. Holographic information can be more continuous and less binary than its EM counterpart, so that errors are not 0-or-1 events but differences in degree. In this respect, holographic files retention and extraction helps calculators to act more like the human brain than computers with traditional electromagnetic media.
The capacity of holographic technology to function associative retrieval opens up not only new techniques of investigating for information, but furthermore new possibilities for calculator knowledge and virtual reasoning. Since holographic development enables comparison of macro files patterns using parallel processing and associative extraction, it may examine large quantities of information to identify macro-level links that would be cumbersome, if not unobtainable, to perceive with distinct, serially-defined programs.
A "holobot" is a robot that uses holographic engineering. A “Category I” holobot is a directing three-dimensional photo without the potential to interact with the real world using touch/force or artificial reasoning based on holographic development. A “Category II” holobot is a positioning three-dimensional construct that is able to respond with the real world using touch/force, but does not have virtual rationality constructed on holographic science. A “Category III” holobot is a pushing three-dimensional construct that can interact with the real world using touch/force and also has artificial intelligence constructed on holographic invention. Category III holobots learn through innovative identification of important patterns in gigantic quantities of input from their surroundings.
One of the greatest obstacles in the commercial accomplishment of holographic technology is the creation of best elements and patterns for high-capacity, fast-access, secure optical storage media. Candidate elements incorporate: high-sensitivity photochromic and photochemical polymers; photosensitive crystals such as lithium niobate; organic photopolymers; and goggles.
Holographic engineering has been in use for decades for artistry and recreation. Even simple holograms with alternating views may be stunning works of artistry whose two-way qualities engross the viewer. Dynamic holographic images in high-technology amusement park attractions routinely engage and thrill riders. Holographic research is already being used to record holographic DVDs over a hundred gigabytes in size. Future holodisks and holographic cubes might store up to a terabyte. In the coming decade, current holographic technology applications will come from the hybridization of computer game playing, web connect with, and television. Some applications will be multi-user, responding, three-dimensional pleasure experiences.
Using action detection and tactile force resistance, a hologlove allows a user to contact and assemble three-dimensional holographic objects. Hologloves may be incorporated into holographic product development and hologames.
Holographic Television (HoloTV) has: moderate to high two-directional causation; is real time; ranks high on the perceptual perspective with surrounding three-dimensional illustrations and sound; wide (or total) domain of vision of high-quality pictures and three-dimensional sound; and common source distribution. The key technological challenge in the discovery of holographic television is the generation of a rippled illumination emitting veneer that varies in structure. Current holograms use solid, rippled surfaces that do not modification configuration. The evolution of innovative materials built on nanotechnolgy that quickly change shape might improve to answer this challenge and make holographic television commercially doable.
The present state of the art for holographic television (HoloTV) systems is projection of radiant photos onto a pane of glass spread with a translucent film, forming the pipe dream of an image suspended in mid-air. Future holoTV systems will very possible be able to render full three-dimensional images in mid-air without a projection surface of any time.
Even now, rudimentary usages of holographic technology are beginning to be used in private residences. For example, holographic lighting that creates the illusion of three-dimensionality is already being used for home adornment. There are predicted to be numerous dynamic applications of holographic research in the pleasure area such as holographic, three-dimensional calculator rendered, televisions, motion pictures, synthetic reality, gaming, and simulations.
Holographic development is already widely used for security products and services. Holograms are much more difficult to forge than patterns (even ornate ones) made with standard two-dimensional printing techniques. Accordingly, holograms are used on identification cards, bank cards, financial securities, passports, tickets, drugs, and critical documents and consumer goods to reduce forgery. Some countries are already requiring holographic protection labels on drugs and alternative medical-realted products. Most protection holograms are now made by embossing a order into an upper “rippled” stratus that is applied over a limited “mirrored” layer. Light reflected off the lower stratus and refracted in the upper layer creates the holographic photo.
There are numerous capability products and services of holographic information systems in the general area of media and imaging. "Holocams" will use holographic data saving and recreation to archive and virtually display three-dimensional visual environments. Holographic data processor displays and interfaces, consisting of gesture recognition systems, will enable much more natural human-computer interaction than is possible with current two-dimensional displays and keyboard/mouse. Holographic visualization with temporal gated pulses will enable clear viewing of objects embedded in illumination refracting matter such as body fluid or viscous atmospheres.
Holographic technology is commencing to be used to swell the range of connection from humans to computers. Traditionally, the most common method of communication from humans to computers has been touch through keyboard, mouse, joystick, or touch-screen. Holographic technology expands the horizon of human-to-computer touch-based connection. Devices using holographic technology may render holographic keyboard images in the air and record when human fingers intersect with those illustrations. This allows touch-based media to escape the dimension limitations of an input device. In the coming years, pocket scale hardware with holographic technology could offer desk-top-size holographic keyboards. Holographic technology might additionally be practical to the progressing area of gesture recognition, allowing much more natural human-computer interaction.
In the domains of telecommunications and schooling, teleconferencing and distance schooling developments featuring two-dimensional screen images will be succeeded by three-dimensional, responding holopresence systems. Holographic research is already being practical to “HoloCells” (holographic cellular phones that record and reproduce three-dimensional, real-time images of the communicating people that will potentially be observed from unique angles).
The number of realized and promise applications of holographic technology in the field of human-to-human communications is additionally increasing quickly. A holocam records and conveys radial three-dimensional real-time images from a focal point using holographic engineering. A holoviewer projects these pictures for remote viewing. Holocams and holoviewers will probably be integrated into network connect with, television, and cell phones by 2010. New communications systems grounded on holographic technology are additionally possible with applications in both personal and business media. Holographic technology could also enhance the transmission quickness and channel capacity for data transmission systems built on fiber optics.
In the domain of marketing, holomarketing or “holopromotion” is the application of holographic development to three-dimensional, high-resolution advertising. Marketing and purchasing functions will potentially be combined in interactive holograms that both spark consumer attention and sell a product on the spot. Holoactive kiosks and vending tools that project consumer-interactive likenesses numerous times their dimension will take up much less space than standard kiosks and vending mechanisms.
In the discipline of medical display, HT (HoloTomography) is the creation and interpretation of three-dimensional health-related images. Basic holotomography involves unmoving illustrations constructed from usual visualization mechanisms such as CT (Computerized Tomography), MRI (Magnetic Resonance Imaging), and PET (Positron Emission Tomography). Advanced holotomography involves moving, interactive three-dimensional visions from dedicated holographic imaging machines.
In the sector of health care, holographic photo-rendering and tomography will probably become core to computer-assisted biomedical diagnosis and healing. The capacity of gated holography to generate sharp images of items within translucent fluid could make it the picturing modality of choice for a large number of biomedical applications. Also, biomedical researchers are designing applications of holographic engineering for the creation of three-dimensional computer models of patients’ organs and external features. These holographic models are then used to manufacture personalized implants and prostheses.
Holocartography and holotopography apply holographic research to the production of three-dimensional maps for positioning and discovery. Applications in the subjects of navigation, aerospace and defense may consist of directional guidance and navigation. Holographic simulations of novel goods may be discovered and viewed in an only a fraction of the time required by physical testing and modeling processes. One of the roadblocks to large-scale market use of holographic technology is the resource of compatible storage, processing, and render hardware. However, costs for liquid crystal projects and solid-state camera chips are decreasing. We are likely on the verge of large-scale commercialization of holographic science.
