ABSTRACT:
A flat field laser recorder includes means to direct a beam from a laser through an acousto-optic light modulator, an acousto-optic light deflector/modulator, and a beam scanner, to scan-lines on a linearly-moving light-sensitive film. The acousto-optic light modulator is operated by electrical oscillations which are amplitude modulated by a video information signal. The acousto-optic light deflector/modulator is operated by electrical oscillations which are amplitude modulated to provide an automatic brightness control of the beam, and are frequency modulated to provide an automatic scan-line spacing control. In addition, a plurality of simultaneous oscillation frequencies are selectively applied to the deflector/modulator to provide beam spot elongation control in the direction perpendicular to the scan-lines.
