Abstract:
1. An exposure device comprising: a light source that emits light beams for illumination; a spatial light modulator in which a plurality of pixel portions whose respective light modulation states change in correspondence to control signals are two-dimensionally arranged and which modulates, per pixel portion, the light beams that are incident at the plurality of pixel portions from the light source; a microlens array in which a plurality of microlenses are two-dimensionally arranged at a pitch corresponding to the plurality of pixel portions and which condenses, per microlens, the light beams modulated by the pixel portions; and a head portion where incident ends of a plurality of optical fibers whose emission ends are tapered are two-dimensionally arranged at a pitch corresponding to condensing positions of the plurality of microlenses, wherein a photosensitive material is exposed by evanescent light leaking out from the emission ends of the plurality of optical fibers.
