Dynamic Change of Focus for True 3-D, Scanned Retinal Displays
Introduction Generating true 3-D computer displays will enable the creation of more realistic and informative images, allowing improved functionality when relying on visual display data. Technology description Researchers at the UW have developed the use of optical elements to dynamically adjust the wavefront of scanning beams of light for scanned retinal displays. These elements adjust the phase of the wavefront spatially across the beam, changing the focal point of the beam. The virtual retinal display (VRD) scans a collimated beam of light into the eye to form virtual images. These faster elements allow more complexity to the 3-D image display. The virtual image will not be perceived at infinity, but a close 1/3 meter from the viewer. Business opportunity This device will enable appropriate stereoscopic views to each eye, with the viewer able to perceive true three-dimensional (3-D), virtual images with scanned retinal displays. Potential applications include medicine (non-invasive imaging, telemedicine, and training), space and military (remote operation, navigation, and simulation) and entertainment (viewing movies and video games). Stage of development A prototype has been made, feasibility demonstrated, and performance data obtained.
