Small Projector Array Display System

The goal of achieving large field of view, near-eye limiting resolution display systems for training solutions has always been elusive. High costs associated with all elements of such systems have been prohibitive for virtually all programs. Using ultra-high resolution projectors to reduce the number of image generation channels yields projector costs of over $ 20,000 per channel. Using consumer resolution projectors requires many more projectors at a cost savings, but the added cost of image generator channels comes at the expense of $ 15,000 or more per added channel. A solution is needed that can reduce both projector cost and image generation channel count. The proposed solution herein would take advantage of very low cost, pico-projectors to provide the display projection component. While there would be many such devices, they could be clustered to drive multiple projectors from a single image generation channel to minimize those costs. In order to yield a high fidelity end result from these low cost devices, alignment system and enhanced image post processing requirements are necessary. If these processing needs are assigned to COTS graphics processing cards, both high resolution and field of view can be achieved economically.
