Abstract
NOVELTY - The image spot generator includes a rotary deflector (36) to which a code disc (32) is fixed. The code disc carries markings (41) for producing a correction clock. The variation in angle between the clock generating regions of adjacent markings with respect to a center of rotation is inversely proportional to the variation in line exposure speed of an imaging unit. DETAILED DESCRIPTION - A digital exposure apparatus for exposing a straight line using an acousto-optic modulator, and correcting for distortion using the image spot clock generator is also claimed. USE - For exposure of lines on a light sensitive material. ADVANTAGE - The clock generator is compact and requires little adjustment during manufacture or maintenance. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the deflector device. Code disc 32 Deflector 36 Markings 41
