    摘要： A laser sintering apparatus for realizing high-speed and high-precision forming. When a first position of an exposure unit is decided by an XY-positioning mechanism, a micromirror of a DMD is turned on and off in accordance with image data in a region corresponding to the first position and a laser beam in a predetermined region including ultraviolet is supplied to the DMD and modulated for each pixel in accordance with image data. A laser beam reflected in the direction of a reflection mirror is reflected therefrom in the direction of a surface of a powdered body. A region having a predetermined area on the surface of the powdered body is exposed by the laser beam, and the exposed portion is thereby cured. Similarly, by repeating movement of and exposure with the exposure unit, the entire surface of the powdered body is exposed.

    摘要： 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. Since the number of optical fibers is few, the light-emitting region is further decreased when the optical fibers are arrayed.

    摘要： Provided are an optical correcting system which can form a linear image or illuminating light having a substantially uniform light intensity distribution without reducing the efficiency of use of light, and an exposure head which can perform excellent exposure by using the linear image or the illuminating light. Light flux from a light source is collimated by the function of a collimator lens, and the collimated light flux enters into an optical correcting system for correcting light intensity distribution. The optical correcting system for correcting light intensity distribution changes the width of the light flux at the exit position at which each collimated light flux exits so that the light intensity distribution of a linear image is uniform when the collimated light flux is formed into the linear image. A change of the widths of the light flux allows utilizing the light flux at the midsection generally having a high light intensity distribution for the peripheral having an insufficient light intensity, thereby uniformalizing the light intensity distribution of the linear image without reducing the efficiency of use of light as a whole.

    摘要： An optical fiber of a bundled fiber light source is an optical fiber whose core diameter is uniform but whose emission end cladding diameter is smaller than an incidence end cladding diameter thereof, and a light emission region thereof is made smaller. An angle of luminous flux from this higher luminance bundled fiber light source, which passes through a lens system and is incident on a DMD, is smaller, i.e., an illumination NA is made smaller. Thus, an angle of flux which is incident on a surface that is to be exposed is smaller. That is, a minute image formation beam can be obtained without increasing the image formation NA, focal depth is lengthen.
