A practical and simplified method will be studied and developed for the video display of three-dimensional (3-D) information with the following design goals: no attachments to be worn by viewer, 3-D video display in full color, low cost system, largely compatible with standard video technology, no moving parts, and no dependence upon special physiological factors that may not be shared by all viewers. The approach involves an innovative combination of video technology, lens design, and optical alignment techniques. Computerized ray tracing will be used for the special lens design. A prototype for use with video camera display will be built to verify the expected performance. These results will be used to arrange licenses with user companies for the commercialization after completion of Phase II. IN Phase II, the design will be simplified for cost reduction and easy maintenance. Provisions will be added for viewing computer generated graphics.
