    摘要： A method for correcting recording positions of light beams scanned by a light beam scanning apparatus, in which at least one of plural light beams is deflected by an optical deflecting device and all the plural light beams are combined and scanned by a common scanning optical system. The beam position correction data for the optical deflecting device for keeping positions of the light beams constant is obtained by detecting the beam positions before the scanning optical system. The recording positions of respective light beams on a recording surface is also detected to obtain an additional correction data for correcting deviations of the recording positions due to uneven optical power distribution of the light beam or astigmatism of the scanning optical system. The additional correction data is added to the beam position correction data to obtain the final correction data, by which the optical deflecting device is controlled.

    摘要： A synchronizing light beam applied to a reference grating passes through the reference grating as a pulsed synchronizing light beam, which is converged by a convex entrance surface of a light guide rod onto a rear surface thereof. The synchronizing light beam is then diffused and reflected by a diffusion surface on the rear surface, and applied to photodiodes on respective opposite ends of the light guide rod. The photodiodes converts the applied light to a synchronizing signal.

    摘要： Corrective signals for canceling out a dynamic deformation of the reflecting surface of a rotary scanning mirror are applied to X and Z electrodes of an electro-optic lens. Based on the supplied corrective signals, the electro-optic lens controls the refractive index of a light-transmissive element to refract a laser beam in a direction to eliminate an excessively converged or diverged condition of the laser beam due to the dynamic deformation of the reflecting surface of the rotary mirror. The spatial vector of the corrective signals supplied to the electro-optic lens rotates in synchronism with the rotation of the rotary scanning mirror. Therefore, the laser beam which passes through the electro-optic lens and is reflected by the reflecting surface forms a beam spot on a film, which stays focused at all times irrespective of the angular displacement of the rotary scanning mirror.

    摘要： A light beam emitted from a light source passes through a spatial light modulation device, at which a plurality of unit elements for respectively modulating incident light beam are two-dimensionally arrayed, and a microlens array, at which a plurality of microlenses corresponding to the unit elements are arrayed, and is focused on an exposure surface. A four-part detector, which is structured by four diodes, is disposed on the exposure surface so as to correspond to four pixels which are present at one corner of the exposure area. Relative mispositioning between the spatial light modulation device and the microlens array generates a difference in respective detection signals of the four diodes. Thus, an offset between the spatial light modulation device and the microlenses can be detected. Positional adjustment of the microlens array is performed on the basis of a detected offset amount.

    摘要： A spatial light modulator performs spatial light modulation of light produced by a light source. An image-side telecentric image forming optical system forms an image of a two-dimensional pattern of the light, which has been obtained from the spatial light modulation, on a photosensitive material. An axial air separation adjusting section is located between the image forming optical system and the photosensitive material. The axial air separation adjusting section alters an axial air separation between the image forming optical system and the photosensitive material and thereby adjusts a focusing point at the time of the formation of the image of the two-dimensional pattern of the light.
