Earth Virtual-Environment Immersive Scene Display System, Phase I

Completed Technology Project

Project Introduction

Earth Virtual-Environment Immersive Scene Display System, Phase I
In response to the NASA need for a free-standing immersive virtual scene display system interfaced with an exercise treadmill to mimic terrestrial exercise experience in space, Physical Optics Corporation (POC) proposes to develop a new Earth Virtual-environment Immersive Scene (EVIS) display system based on omnidirectional image projection and a wraparound multiplexed holographic collimating projection screen. A single unique, high-resolution omnidirectional wraparound image projector projects continuous wraparound imagery onto thin, curved, three-color-(RGB)-multiplexed holographic optics, which collimate the projected light into a virtual image. EVIS will thus display a greater than 180 degree (up to full 360 degree) free-standing FOV of flowing virtual earth scene to a crew member on a treadmill. Without multiple projectors, bulky optics, or a tiled screen, EVIS will be compact, lightweight, and power-efficient. It is producible at low cost by integrating commercially available microdisplays for the omnidirectional projector and by mass producing the multiplexed holographic collimating screen by means of established POC technologies. In Phase I POC will design in detail an EVIS display system for a treadmill, and fabricate a proof-of-concept model to demonstrate feasibility. Phase II will focus on optimizing both the material technology and components so that a fully operational prototype is completed. More »
