Abstract
This paper describes techniques for the implementation of high speed, high resolution laser line and/or raster scanned recorders through use of acousto-optic deflection and modulation. A rationale for the design of scanned imaging is presented, discussing such topics as horizontal and vertical, modulation transfer function (MTF), exposure requirements when scanning with a Gaussian spot, and the effect of film characteristics (gamma). A descrip-tion of several working systems is presented. These include the LR-100/200 Laser Recorder which involves the recording of 875 line television imagery on 8 and 16 mm dry processed film, and a high resolution line scanner (4000-6000 spots) that was brassboarded solely with the use of acousto-optic components. The heart of each of these systems is a patented acousto-optic device called the chirp scanner which permits high resolution, high speed scans with literally zero flyback time. This device also forms the basis of a future system capable of direct digital recording at a 150 to 200 Mbit rate.
