What is a virtual retina view?

The Virtual Retinal Virtual Display (VRD) is a display system mounted on the head that projects a picture directly on a human retina with low -energy lasers or LCD. VRDS can give the user an illusion of a typical screen size display that floats in the air for several feet far away. In principle, technology can provide full -color dynamic displays with high resolution, but in practice the components are necessary to achieve the full potential of technology either very expensive or simply not built. Although this technology was invented by the University of Washington in the Technology Interface Technology Lab (HIT) in 1991, the development did not start until 1993; This technology still needs many improvements and has only been commercialized in specialized industries on the exhibition market, such as repairing cars and some parts of the army.

VRD unit consists of 4 modules; driveTronics to break down the incoming source image into the information current, a source of light composed of laser or LED), a scanner bank composed of horizontal and vertical scanners and a lens to extend the image through scanners. As on television, scanners quickly oscillate left or right or down-naHor and selectively allow colors in precise configurations that produce a 2 mm x 2 mm field with high resolution. Then the lens acting as an expander increases the size of the image to something like 18 mm x 18 mm, allowing a larger and more natural image. The pixels field is then projected on the eye, where the eye lens focuses on the retina. In addition to clicking into the optical nerve itself, there may be no more effective way to view the image.

The retina virtual display is highly efficient in terms of energy consumption and requires much less energy than LCD logs used commonly used in today's mobile devices. VRD display uses forces. BecauseVrd displays project images directly on the retina, providing a sharp and clear image regardless of external lighting conditions. VRD displays require a fraction of the conventional imaging devices that allow lighter and more elegant mobile devices, with high demand for today's electronic market. VRD shows the strong potential for replacing LCD screens in mobile phones, pocket computers, handkerchiefs, and ultimately larger computers such as laptops.

The

VRD technology is only commercialized by the Technology Society based in Seattle Microvision, Inc. So far, two products include nomad (TM), a VRD mounted system that displays a monochrome overlap of relevant information for a given task and Flic (TM), a laser molding code. Nomad uses Windows CE and 802.11b wireless protocol. Because the VRD components show the cost reduction and the manufacturing processes used to create them, the distributed product will surely expand to the sizeme a big market.
