Virtual Retinal Display
The Virtual Retinal Display (VRD) is a personal display device. The VRD scans light directly onto the viewer's retina. The viewer perceives a wide field of image view. Because the VRD scans light directly on the retina, the VRD is not a screen based technology. The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality, the image is on the retina of its eye and not on a screen. The quality of the image he/she sees is excellent with stereo view, full color, wide field of view, no flickering characteristics. The aim is to produce a full color, wide field-of-view, high resolution, high brightness, low cost virtual display. This technology has many potential applications, from head-mounted displays (HMD's) for military/aerospace applications to medical society.
