Abstract
An image scanning and recording system includes a recording unit for duplicating and recording halftone images on a photosensitive material. The recording unit comprises an acousto-optic light modulating element including a plurality of ultrasonic wave exciting portions disposed side by side on a single acousto-optic medium. The ultrasonic wave exciting portions independently, modulate incident light into a plurality of modulated light beams in response to image signals from photoelectrical scanning means. A scale-down optical system then reduces the diameter of the plurality of modulated light beams, and a plurality of light transfer elements transfer the light beams from the scale-down optical system to a focussing lens system to be projected therefrom onto a film mounted on a recording cylinder.
