Abstract
A pattern generator for simulating image generation is disclosed which pets the testing of wide angle, non-programmed visual display systems including, for example, a 360.degree. non-programmed visual display system. The program generator produces a pair of composite signals, the first of which may be utilized by an annular projector to project upon a screen a sawtooth waveform pattern, and the second of which may be utilized by the annular projector to project upon the screen a checkerboard pattern so as to facilitate the testing of wide angle visual display systems.
