ABSTRACT:
The improved apparatus for exposing a light-sensitive material to recording light modulated in accordance with an image to be recorded includes a source of recording light, a multi-channel spatial light modulating element using a liquid crystal, imaging optics with which the recording light modulated with the spatial light modulating element is imaged on the light-sensitive material, and apparatus for adjusting the temperature of the spatial light modulating element. This exposing apparatus ensures that image of high quality (high resolution) can be recorded at high speed by performing multi-channel exposure with an inexpensive and simple device design.
