Mechanical limitations dictate that high speed oscillating scan mirrors, required for video rate scanning, must be driven sinusoidally rather than at constant velocity. We have designed a diffractive corrector element that removes the resultant distortion in the scan field by optically converting the sinusoidal scan into a linear one
