abstract="The most challenging aspect of flight simulation is representation of the visual scene as it appears through the aircraft windshield. A review is made of the techniques that have been used and a discussion is included of film systems, television cameras and models, and the latest fully digital systems. Helicopter flying at low altitude necessitates the generation of a large amount of visual detail over a very large field of view. Currently in development is a system that uses a scanning laser beam over a detailed model of the terrain over which the simulator is flying and producing a video signal by using a bank of sensitive photodetectors. For display, a direct-writing laser projector is used to cover a field-of-view of 180 deg x 70 deg in full color. Prototypes of both the image generator and the projector have been built.<p />",
