摘要： An optical scanning unit includes a light source that emits a light beam, a light deflector that deflects the light beam from the light source, and a scanning optical system that focuses the light beam deflected by the light deflector on a scanning surface. The light beam from the light source is at an angle in a secondary scanning direction with respect to a normal to a reflecting surface of the light deflector. At least one surface of the scanning optical system does not have a curvature in the secondary scanning direction, being tilted and decentered in the secondary scanning direction.

摘要： In order to provide a data processing technique for easily and suitably executing an integrating process for a plurality of image groups obtained successively from different directions against the object to be the base for generating a three-dimensional shape data of an object, while the object SB in a first posture placed on a rotary stage is being rotated, images of the object SB are successively photographed by a photographing device so that a first image group is obtained. The posture of the object SB is changed into a second posture, so that a second image group of the object SB is obtained similarly. Corresponding points Sp1, Sp2, Sp3 and the like of the object SB are specified on a partial first image extracted from the first image group and a partial second image extracted from the second image group. Conversion parameters of the first and second image groups are calculated from the information about the specified plural corresponding points, so that the integrating process is executed. As a result, the integrating process for the plural image groups can be executed easily and suitably.

摘要： When a scanning start position set signal is input in an area image sensor, the content is transferred to a vertical scanning circuit, and the scan start position is set. Image of a desired row is read by horizontal scanning. Then, one shift signal for vertical scanning is input, the position of scanning is shifted by one row, and horizontal scanning is performed. Thus image of the next row is read. By repeating this operation, a desired strip-shaped image is read. The shape of the object is determined and when a portion is determined to have complicated shape, the image data is input by means of a lens having long focal length, and image data of other portions are input by means of a lens having short focal length. By putting together a plurality of input image data, image data as a whole is generated.

The phase type optical element has a phase distribution so that a first ratio of the peak intensity of side lobe laser beams to the peak intensity of main lobe laser beams in a beam intensity profile at a focal position of the laser beam condensing element is greater than a second ratio of the peak intensity of side lobe laser beams to the peak intensity of main lobe laser beams in the beam intensity profile at the focal position of the laser beam condensing element when it is assumed that the phase type optical element is not disposed.
