Holographic Memory

HoloROM (Holographic Read-Only-Memory) enables parallel- processing for rapid access to large quantities of data. Holographic invention is constructed on the beam design constructed by interference between two crossing light beams: a "signal" (or "object") shaft that retrieves material that was recorded within optical memory media; and a "reference" beam. The three-dimensional photo made by this light pattern is a "Hologram." Holographic development is a critical part of the general domain of interferometric invention.

Before further discussion of holographic technology products and services, we should review the basics of how holographic images are recorded in, and retrieved from, optical media. In order to record and retrieve a meaningful holographic image, the converging illumination beams must be "coherent." Coherent rays are ones in which the illumination ripples are ordered and synchronized. Without coherence, one just gets the three-dimensional equivalent of the "white noise" that appears on a television that is not tuned to a station. Lasers have coherent beam undulations and are commonly used for holographic technology. Generally an isolated laser beam is split through a semi-reflective mirror into the signal shaft and reference ray to ensure synchronization of the shafts.

To record the illustration of an item using holographic invention, the signal shaft is shown through an expander lens onto the object 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 image 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 imprint the original hologram. This produces refraction within the media and recreates the holographic vision in three dimensions exterior to the media. The holographic image materializes in three dimensions due to observed parallax. For more: The Aprilis HoloSensor.

The way in which two-dimensional sources render three-dimensional images may be preferred understood by considering how one-dimensional sources can render two-dimensional likenesses. Consider the pattern created by converging undulations on the veneer of a pond when one drops two stones into the water. Each stone basically interacts with the veneer of the water at one point an one-dimensional wave source but the waves radiate out on the outside of the water in two dimensions and their intersection forms a two-dimensional design on the surface. Now consider how a hologram is formed. When illuminated with a reference beam, a stratus of holographic optical media basically interacts with space in a plane a two-dimensional wave source but the undulations spread out out into space in three dimensions and their intersection forms a three-dimensional hologram in space.

To record files using holographic science, a "Spatial Light Modulator" (SLM) encodes a total page of information into the signal beam that is then projected into the photosensitive optical media. As is the case with engraving holographic pictures of objects, the signal and reference light beams intersect and record the data pattern in the optical media. For information recreation, the patterns of light and darkness from the recreated image are reconverted into electronic files using a "Detector Array" (DA). For more Virtual Keypads for Cell Phones.

When holographic files can only be recorded once in optical media, then the media is "Holographic Read-Only-Memory" (HoloROM). When holographic data will generally be repeatedly accessed and altered in real time, then the media is "Holographic Random-Access-Memory" (HoloRAM).

Another reason that holographic files will generally be recorded and read more rapidly than rotating magetic media is that laser shafts, without the inertia of mechanical reading and writing mechanisms, will generally be shifted very speedily.

Holographic data retention and reading additionally has the capability for greater capacity to recover from minor errors. Holographic files can be more continuous and less binary than its electromagnetic counterpart, so that errors are not 0-or-1 events but differences in degree. In this respect, holographic data saving and recreation helps computers to function more like the human brain than computers with traditional electromagnetic media.

In some respects, holographic invention will generally facilitate machines to perceive more like humans do. The human brain processes gigantic bits of input from a largely disorderly biosphere. This enables humans to "make sense of it all." For example, human comprehension starts with particular bits of information received through the eye, but rapidly processes these through an ascending order of increasingly macro-level constructs before the brain infers inferences regarding what it perceives. Similarly, holographic science can assist machines to evolve from lower-level "pixel by pixel" observation to macro-level comprehension and interpretation of complex environmental patterns. This will potentially be particularly feasible with optical neural networks constructed on holographic technology.

A "holobot" is a robot that uses holographic engineering. A "Category I" holobot is a placing three-dimensional photo without the potential to interact with the real world using touch/force or engineered intelligence based on holographic innovation. A "Category II" holobot is a placing three-dimensional construct that is able to engage with the real world using touch/force, but does not have simulated reasoning founded on holographic invention. A "Category III" holobot is a positioning three-dimensional construct that can interact with the real world using touch/force and also has artificial intelligence built on holographic science. Category III holobots learn through innovative identification of worthwhile patterns in massive quantities of input from their surroundings. More Nanomedicine.

Although there is serious capacity in terms of fast access and high retention density for holographic data systems, many challenges remain concerning the composition and form of the retention media. Candidate media matter consist of: high-sensitivity photo-chromic and photochemical polymers; and photo-sensitive crystals (such as lithium niobate) and lenses.

Holographic engineering has been in use for decades for art and entertainment. Even introductory holograms with alternating perspectives will generally be attractive works of design whose engaged qualities engage the viewer. Dynamic holographic images in high-technology amusement park attractions routinely engage and thrill riders. Holographic science is already being used to record holographic DVDs over a hundred gigabytes in scale. Future holodisks and holographic cubes may save up to a terabyte. In the coming decade, new holographic engineering products and services will come from the hybridization of computer game playing, internet connect with, and television. Some applications will be multi-user, interactive, three-dimensional pleasure experiences.

Using motion detection and tactile force resistance, a hologlove allows a user to handle and assemble three-dimensional holographic objects. Hologloves will generally be incorporated into holographic product innovation and hologames.

Holographic Television (HoloTV) has: moderate to high two-directional causation; is real time; ranks high on the perceptual scale with surrounding three-dimensional images and sound; wide (or total) field of vision of high-quality pictures and three-dimensional sound; and common source distribution. The fundamental technological challenge in the exploration of holographic television is the construction of a rippled light emitting outside that modifies in shape. Current holograms use solid, textured surfaces that do not modification location. The evolution of original elements constructed on nanotechnolgy that quickly change shape could improve to respond to this challenge and make holographic television commercially realistic. Also see -- Virtual Reality.

The contemporary state of the design for holographic television (HoloTV) systems is projection of bright likenesses onto a pane of glass coated with a translucent film, creating the illusion of a likeness suspended in mid-air. Future holoTV systems will likely be able to project full three-dimensional images in mid-air without a projection exterior of any time.

Holographic development is commencing to be used to expand the range of connection from humans to computers. Traditionally, the most common method of conversation from humans to machines has been touch through keyboard, mouse, joystick, or touch-screen. Holographic technology expands the horizon of human-to-computer touch-based media. Devices using holographic science can shine holographic keyboard images in the air and record when human fingers intersect with those photos. This allows touch-based conversation to escape the dimension limitations of an input device. In the coming years, pocket dimension hardware with holographic technology might offer desk-top-size holographic keyboards. Holographic technology might additionally be applied to the expanding domain of gesture recognition, allowing much more natural human-computer interaction. Other MIT Spatial Imaging Lab.

The number of realized and promise uses of holographic technology in the sector of human-to-human data transmission is furthermore increasing quickly. A holocam records and conveys radial three-dimensional real-time images from a focal point using holographic science. A holoviewer projects these pictures for remote viewing. Holocams and holoviewers will probably be integrated into internet obtain, television, and cell phones by 2010. New telecommunications systems constructed on holographic technology are additionally possible with applications in both personal and business telecommunications. Holographic innovation may furthermore upgrade the transmission quickness and channel capacity for communications systems based on fiber optics.

In the sector of marketing, holomarketing or "holopromotion" is the application of holographic technology to three-dimensional, high-resolution advertising. Marketing and purchasing functions will potentially be combined in interactive holograms that both spark consumer interest and sell a product on the spot. Holoactive kiosks and vending machines that project consumer-interactive photos several times their scale will take up much less space than usual kiosks and vending mechanisms.

In the field of medical imaging, HT (HoloTomography) is the creation and interpretation of three-dimensional healing images. Basic holotomography involves unmoving images assembled from usual photo-rendering technologies such as CT (Computerized Tomography), MRI (Magnetic Resonance Imaging), and PET (Positron Emission Tomography). Advanced holotomography involves moving, two-way three-dimensional photos from dedicated holographic imaging machines.

In the area of medical practice, holographic photo-rendering and tomography will probably become core to computer-assisted health-related diagnosis and curing. The potential of gated holography to form sharp images of things within translucent fluid could make it the picturing modality of choice for a large number of biomedical applications. Also, biomedical investigators are creating applications of holographic innovation for the creation of three-dimensional computer models of patients' tissues and external features. These holographic models are then used to make personalized implants and bionics.

Holographic invention will likely furthermore be used for guidance. For aircraft navigation, holographic systems project maps, navigational graphics, and targeting information. Three-dimensional air traffic control is a promise future application. With increased computing power and high engineering in land vehicles, holographic-assisted navigation may be commonly used for land transportation as well. Already, prototypes are under development for car dashboards that include holographic projects.

Applications in the subjects of travel, aerospace and defense may incorporate directional guidance and direction.

Design is prime to engineering, innovative product innovation and testing, architecture and construction, genetics and nanoscale pharmacology, chemistry and nanoscale modeling, medical practice and bionics, the clothes industry, the fine arts, and different locations as well. Holographic invention can help design for: movement of three-dimensional experimental designs of molecules or biological structures; creating electronic processors; and alternative design-related applications.

Holographic technology is an evolving subject with today's and potential applications in amusement, protection, information memory and retrieval, artificial intelligence, human-computer interaction, medical practice, guidance, innovation, and athletics. While some of the above applications are not yet commercially feasible, progress is likely to be driven by the creation of low cost lasers and original media generated by nanotechnology By the year 2010: holographic disks may supplant two-dimensional files saving media; holographic input and output tools may become the basic means of human-computer interaction; and holoputers could improve upon conventional machines with just magnetism-based memory.
