    摘要: In an exposure head of the invention, plural first micro-focusing elements are arranged in a first microlens array so as to correspond to plural micromirrors in a DMD. An aperture array that includes plural apertures arranged so as to respectively correspond to the plural first micro-focusing elements is disposed. The apertures allow only main portions of Fraunhofer diffraction images to be transmitted therethrough. The main portions of the Fraunhofer diffraction images transmitted through the apertures are imaged on an exposure plane by second micro-focusing elements of a second microlens array. According to the exposure head of the invention, cross-talk light and scattered light can be effectively reduced, and beam diameters of beam spots projected on the exposure plane through the apertures can be adjusted to a required size.

    摘要: An imaging head faces an imaging surface and is relatively moved along the scanning surface in a predetermined scanning direction. The imaging head includes an imaging element group and an alteration section. The imaging element group is structured by a plurality of imaging elements, which are arranged two-dimensionally in a plane substantially parallel to the imaging surface. The imaging element group generates a group of image pixels at the imaging surface in a two-dimensional arrangement which is inclined, as a whole, at a predetermined inclination angle with respect to the scanning direction. The alteration section alters a number of image pixels in a direction which is inclined from the scanning direction by the inclination angle, on the basis of a difference between the predetermined inclination angle of the imaging element group and an actual inclination angle of the image pixel group.

    摘要: In a light beam scanning system, a beam shaper shapes light beam emitted from a light source. The shaped light beam is deflected by a deflector to scan a surface in a main scanning direction.

    摘要: At least one plane diffraction grating is formed on a rotatable plate, and a light beam is made to impinge upon the plane diffraction grating. The first-order diffracted light component and the minus first-order diffracted light component of the light beam diffracted by the plane diffraction grating are reflected by use of many plane reflection surfaces and guided again to the plane diffraction grating so that, after the reflected light beams are diffracted again by the plane diffraction grating, the light beams diffracted again become parallel with the original light beam incident on the plane diffraction grating. The parallel light beams diffracted again are focused by a focusing lens onto a scanning surface, so that the scanning surface is scanned with the focused light spot along a bow-free straight scan line as the rotatable plate is rotated.
