摘要： A spatial light modulator has a plurality of grating elements. Each grating element can be switched between a diffracting state and a reflecting state, and only zeroth order light beams from the spatial light modulator are directed onto photosensitive material. An irradiation position on the photosensitive material is moved in a direction perpendicular to a width direction corresponding to an arrangement direction of the grating elements. The minimum line width on the photosensitive material corresponds to a width of a predetermined number of grating elements where the predetermined number is two or more. Each group of grating elements which are spatially continuously in the diffracting state or spatially continuously in the reflecting state consists of the predetermined number of grating elements or more while writing is performed. This makes it possible to appropriately record an image on the photosensitive material at high addressable resolution.

摘要： The present invention is a system and method for three dimensional machine vision including a projector and camera. The projector casts a structured light Quadratic Residue Bar Code on the surface to be mapped. The camera then images the surface. The projected image is shifted, and the process is repeated a number of times, according to the particular arrangement selected for the structured light Quadratic Residue Bar Code. The image data collected from this series of images is then processed by relatively simple matrix operations to determine the location of each camera pixel in three dimensional space.

摘要： A beam light scanning apparatus capable of reducing influences of variations in characteristics of circuits disposed in a signal path extending until a laser driver and speeding up image data transfer for scan and exposure. Data of each line is distributed by an image data I/F into data trains of two channels, i.e., an odd-numbered pixel train and an even-numbered pixel train. The data in the two-channel trains are written by writing units into a plurality of memories in parallel for each of the trains in response to a line sync signal. During the same processing cycle as that for the writing, the data are read out of the memories in parallel by reading units. The data of two channels are combined by a multiplexer into a data train in the original order of pixels in each line, and a driving signal based on the combined data is generated by a PWM. A laser is driven by the driving signal.

摘要： A method or system is provided for producing a charge image on an intermediate carrier of an electrophotographic printer or copier. A character generator having a plurality of light sources arranged in at least one row in groups is provided. A separate functional unit is provided for each light source group for control of the light sources. The functional unit is connected with a central control unit, the functional unit comprising an address system via which it can be activated, and a control unit. The light sources of each group are controlled by said control unit assigned to the functional unit. The at least one row of light sources is imaged onto the intermediate carrier as an exposure line, the intermediate carrier being displaced substantially transverse to the exposure line relative to the character generator. A temporal beginning of illumination phases of groups of light sources is selected such that deviations of the exposure line from a target line is reduced.

摘要： An optical beam control device that can suppress deterioration of a laser diode and a photosensitive member is disclosed. Control is performed in such a manner that the luminous energy of emitted light is increased gradually in an initial period from the activation of a laser diode until the first generation of a BD detection signal. The initial period includes an extinction period in which the laser beam is extinguished. Therefore, deterioration of the light-emitting portion of the laser diode and the photosensitive member can be suppressed.
