摘要:
An image exposure device includes an exposure head for forming a desired pattern on a photosensitive material. The exposure head is equipped with a light source for emitting a great number of light beams, a spatial light modulator in which a great number of pixel portions are arranged for independently modulating the light beams emitted from the light source, a micro lens array in which a great number of micro lenses are arranged for individually converging the great number of light beams modulated by the pixel portions, and a total of two or more aperture arrays arranged in the stage before the micro lens array and/or the stage after the micro lens array. Each of the aperture arrays has a great number of apertures for individually restricting the light beams.
