Research in the Development and Application of Nonglass Optical Infinity Display Techniques for Visual Simulation

摘要

Infinity display devices possess many desirable properties than enhance the training value of aircraft flight simulators. In the past, little has been done to apply reflective infinity display techniques to the problem of wide-angle visual simulation. This is primarily because glass mirrors were necessary to obtain the needed optical quality. These mirrors were heavy, fragile, expensive, and took a long time to manufacture. Additional support structures and control systems required by glass mirrors only added to the cost and complexity. Objectives of the nonglass infinity display research program were to study wide-angle display system concepts develop high-quality nonglass mirrors and fabrication techniques, build a prototype display system, and define cathode ray tube characteristics needed for the display. A prototype unit using nonglass mirrors was fabricated having a 120-degree horizontal field of view and a 45-degree vertical field. (Author)
