Abstract:
1. An image recording apparatus for recording an image on a recording medium, comprising: a light source; a light modulator having a plurality of light modulator elements for receiving light from said light source; a holding means for holding said recording medium which is exposed to signal light beams from said light modulator; a photodetector having a plurality of photodetector elements; a recording optics for bringing said signal light beams to said recording medium; a detection optics for bringing the signal beams from said light modulator to said photodetector at a time, the signal beams being subject to beam intensity correction; correction electronics for providing correction data to said light modulator; and a controller for selecting a group of said plurality of light modulator elements, each element of which is selected to be spatially separate from an adjacent one by a distance of n (integer) elements, and sequentially reselecting one group after another until all of said plurality of light modulator elements are selected, wherein each of said plurality of light modulator elements comprises a plurality of ribbon-like diffraction grating members for generating diffracted light beams and a normally reflected light beam.
