A Training System Based on a True Volume Display

Physical Optics Corporation (POC), R&D Division, proposes a training system utilizing a new low-cost full-color real-time true volume display (TVD) which is based on an innovation volumetric concept. The TRC concept synthesizes an image from computer acquired and stored digitized information within the 3-D space of a multilayer screen. The volumetric screen is a stack of 2-D switchable liquid-crystal layers synchronized with a computer-controlled video projector. This permits integration of a real volume image from a sequence of 2-D images projected at a rate that satisfies the stereoscopic systems, produces true volume images with physical depth cues, including distance accomodation, parallax, convergence, and binocular disparities. Implementation of the proposed system for battle-management training-scenario visualization permits true volume, multiperson, off-angle, real-time, full-color viewing of terrain and feature simulation including moving objects, graphics, icons, pointers, atmospheric and special effects.
