ABSTRACT:
A linear beam scanning apparatus especially suitable for recording data on light sensitive film is disclosed herein. This apparatus starts with a modulated beam of collimated light and utilizing a suitable device, preferably a holographic grating scanner, converts this stationary beam to a first continuously scanning beam of light having a particular cross-sectional segment thereof which repeatedly moves, that is scans, from a first point to a second point along an arcuate path. This arcuately scanning beam is then converted by optical means to a second continuously scanning beam which converges to a point and which repeatedly moves, that is scans, from one end of a straight line path to its other end.
