A process and apparatus for measuring angular distortion in an optical imaging system in order to provide a mapping that completely characterizes the distortion of the imaging system involves electronically capturing the image of a test pattern at the image plane of the imaging system, superposing a computer generated reference pattern on the test pattern, and measuring the deviation of the test pattern from the reference pattern at selected areas of the reference pattern.
