Flight Simulator: Evaluation of SODERN Visualization System SVS-14.
Abstract
A solid crystal color light valve display system (to be used on flight simulators) has been developed by SODERN of France for the General Electric Company (GE) under an Air Force Human Resources Laboratory (AFHRL) contract. At the completion of the development phase, a prototype projector, designated as SODERN Visualization System SVS-14, was manufactured. The equipment underwent a series of acceptance tests at the SODERN facility in France and final acceptance testing at AFHRL, Williams AFB. The analysis of the test results showed that the SVS-14 met all important specifications and in some areas even exceeded them. Further experiments with the SVS-14 at AFHRL covered additional engineering evaluations and a human factors study. These tests consisted of a comparison demonstration between the SODERN SVS-14 and the GE PJ5155 projector. Ratings of the visual appearance of the imagery produced by the projectors on a side-by-side arrangement of rear projection screen were in favor of the GE system. However, it was soon found that the performance of the SODERN projector had degraded due to malfunctions of system components. This was caused by a power supply failure that had not been detected prior ot the comparison tests. After extensive onsite repair efforts by SODERN personnel, the performance of the SVS-14 was again evaluated in a side-by-side comparison test with the PJ5155. The results indicated improvements in the quality of video imagery. The image persistence for fast moving objects was about equal for both projectors. (Author)
