Patent number: 7015488Abstract: In an exposure apparatus of the invention, for a spatial light modulator, each of a plurality of pixel portions fewer than the total number of the pixel portions is controlled with a control signal generated according to exposure information. Namely, a part of the pixel portions is controlled without controlling a whole of the pixel portions on the substrate. Thus, the number of pixels in the pixel portions is decreased, and transfer time of the control signal becomes short. This enables modulation speed of the laser beam to be increased and the high-speed exposure to be performed. An incorporated laser light source, in which the laser beams are incorporated and struck on the optical fiber, is preferable to the laser device. By adopting the incorporated laser light source, high brightness and high output can be obtained, and it is preferable to the exposure of the spatial light modulator. Since the fiber array is obtained with few optical fibers, it is low cost.Type: GrantFiled: April 13, 2005Date of Patent: March 21, 2006Assignees: Fuji Photo Film Co., Ltd., Fuji Photo Optical Co., Ltd.Inventors: Hiromi Ishikawa, Kazuhiko Nagano, Yoji Okazaki, Takeshi Fujii, Hiromitsu Yamakawa
