摘要： An optical scanning device includes a light source, a deflector, a random number generator, a selection part, a random number assignment part and an exposure control part. The light source includes a plurality of light emitting parts arranged in a predetermined direction at fixed intervals in a sub-scanning direction. The random number assignment part is configured to assign a random number sequence to each light emitting part constituting a set of target light emitting parts as an index for specifying a timing at which a light emitting time of the set of target light emitting parts is set to a correction value different from a reference value and to update the assignment of the random number sequence at a random number update period. The random number update period coincides with a scanning period of each light emitting part constituting the set of target light emitting parts.

摘要： A printer prints an image on a sheet. A sensor measures a measurement image printed on the sheet. A controller control the printer to print a plurality of test images and a separator on the sheet. The separator is used to control a measurement timing of an external measurement device. The controller controls the sensor to measures the plurality of test images on the sheet, obtains measurement data related to the plurality of test images. The measurement data is outputted from the external measurement device. The controller generates a conversion condition based on a result of measuring the plurality of test images by the sensor and the obtained measurement data. The conversion condition is used to convert the result of measuring by the sensor into a measurement result of an external measurement device.

摘要： A surface-emitting laser includes an active layer on which a spacer layer is disposed, and a reflection mirror disposed on the spacer layer, including a current constriction layer that is a selectively-oxidized layer having been selectively oxidized. The current constriction layer is disposed at a position of a node of a standing-wave of an electric field of light oscillated at the active layer and is disposed away from an interface between the spacer layer and the reflection mirror by an optical distance of one-fourth of an oscillation wavelength at the active layer. The selectively-oxidized layer is made of AlGaAs. The reflection mirror includes at least one AlGaInP layer contacting the selectively-oxidized layer.

摘要： An optical scanning device includes a scanning member, a plurality of light sources, a first reflection mirror, and a second reflection mirror. The scanning member scans incident laser beams in a predetermined main scanning direction. The plurality of light sources emit the laser beams from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction. The first reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams emitted from the light sources. The second reflection mirror is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams reflected by the first reflection mirror toward the scanning member.

摘要： An imaging lens good in mass-productivity, compact, low in manufacturing cost, good in aberration performance is provided by effectively correcting aberrations without greatly varying the variation of the thickness of a curing resin. An imaging device having such an imaging lens and a portable terminal are also provided. A third lens (L3) has a flat surface on the object side, a convex surface near the optical axis on the image side, and a concave aspheric surface around the peripheral portion within the region where a light beam passes. Therefore, it is possible to reduce the other optical aberrations such as distortion and simultaneously to design the imaging lens so that the astigmatism takes on a maximum value at the outermost portion. Hence, the resolutions at low to middle image heights are high. In addition, such a shape does not cause a large variation of the thickness of the third lens (L3) from the region along the axis to the periphery. Therefore, the thickness of the third lens (L3) can be small, and the material cost can be reduced.
摘要翻译：通过有效地校正像差而不会极大地改变固化树脂的厚度的变化，提供了具有良好的批量生产率，紧凑，低制造成本，良好的像差性能的成像透镜。还提供了具有这种成像透镜和便携式终端的成像装置。第三透镜（L3）在物体侧具有平坦表面，在像侧上的光轴附近的凸表面和在光束通过的区域内的周边部分周围的凹非球面。因此，可以减小诸如失真的其他光学像差，同时设计成像透镜，使得像散在最外部分处具有最大值。因此，中低像素高分辨率高。此外，这种形状不会导致第三透镜（L3）的厚度从沿着轴向周向的区域的大的变化。因此，第三透镜（L3）的厚度可以小，并且可以降低材料成本。
