Virtual Image Display for Space Flight Simulator

摘要

This report describes the addition of virtual display imagery to a spacecraft rendezvous and docking simulator. The virtual image display is an optical system which accepts inputs from two image generators and produces a superimposed, virtual image. The major components of the system are a window display, two wide angle rear projection screens, a beamsplitter, a screen drive servo mechanism, and a television projection system. Installation and alignment were accomplished by positioning and leveling the basic structure, attaching the projection enclosures, and installing the window display and projection equipment. Basic operation and performance characteristics, including the relationships of the field of view to the screen size, and the signal voltage to the range, are provided in the report. Recommendations for future improvements in the system, including expansion of the angular field of view and improvement of resolution and brightness, are also given. (Author)
