ABSTRACT:
A flat platen, rotating mirror scanning system is disclosed in which the angular velocity of the rotating mirror is continually varied from end to middle to end of scan to effect a constant speed of scan across the platen surface. This is achieved by providing a mirror drive arrangement which is the mechanical analog of the optical geometry. Conjugate distance changes inherent in flat platen scanning are compensated by a stationary "half-lens" adjacent to the rotating mirror.
