Abstract:
1. An image recording apparatus for recording an image on a recording medium by exposure, comprising: a light modulator having a plurality of light modulator elements of diffraction grating type, in each of said plurality of light modulator elements strip-like fixed reflection surfaces and strip-like moving reflection surfaces being alternately arranged; a light source for emitting a light with which said light modulator is irradiated; a holding part for holding a recording medium on which an image is recorded with signal beams from said light modulator; a transfer mechanism for transferring said holding part relatively to said light modulator; a detection circuit for detecting a state transition of each of said plurality of light modulator elements at a series of points in time; and a control circuit for supplying said each of said light modulator elements with a driving voltage in accordance with said state transition at said series of points in time.
