Abstract

Measurement of resolution, modulation, and contrast on visual displays for flight simulators must be made in order to objectively assess visual system performance. A method of analyzing the image quality of a total visual system is to place a television camera at the pilot's eyepoint and set up to look at a small portion of the visual display. The camera's video output can then be analyzed to determine the level of performance. Resolution and modulation data is obtained on the entire visual system including the display device and image generation system. The observer camera must have several special qualities in order to yield accurate results. High sensitivity is needed because most visual displays have low brightness. A linear response with brightness is also required. By modifying an average-quality vidicon camera with a silicon target vidicon and a unique beam blanking circuit, a low cost camera can be used for resolution and modulation measurements.
