    摘要： A control system for a light-emitting device may include test circuitry, photodetectors, and process circuitry. The test circuitry is configured to sequentially drive individual groups of light-emitting elements in a light-emitting device during a test sequence. Each group of light-emitting elements includes one or more light-emitting elements. The photodetectors are configured to detect an intensity of light present at a plurality of locations of the light-emitting device during the test sequence and generate a detection signal corresponding to the detected intensity of light. The process circuitry is configured to process the detection signals and transmit an adjustment signal based on the processing. The light-emitting elements may then be driven such that at least one characteristic of light emitted by all of the plurality of light-emitting elements is substantially the same at each of the plurality of locations of the light-mixing region.

    摘要： Disclosed are an apparatus, optical scanning device, and a corresponding method of forming images on a photosensitive surface. The apparatus includes a laser raster output scanner (ROS) including laser emitters arranged to simultaneously scan a plurality of laser beams across a single scan line of the photosensitive surface in response to received image data corresponding to pixels in an image to be reproduced, and a controller individually controlling each of the laser emitters to selectively apply one of a plurality of power levels to each of the laser beams based on the image data for each of the pixels, wherein a total power applied by the laser beams for each pixel is determined by a sum of the power levels applied by each of the laser beams.

    摘要： Two integrated multi-beam sources are positioned and disposed such that each emits light toward an optical splitter. The emitted light is polarized such that the splitter brings the optical paths of the two integrated multi-beam sources generally parallel to one another such that the optical system aperture throughput for the two integrated multi-beam sources is roughly the same as for a single integrated multi-beam source. The splitter may be such that a portion of the optical energy from each source is directed into an imaging path and a portion of the optical energy is directed toward one or more non-polarizing splitters and optical sensors for, inter alia, controlling the output of the sources. In various embodiments, the number of splitters, and hence the extent of optical loss, may be reduced by use of a combined polarized and non-polarized splitter, dual polarized splitters, and time-sequenced beam generation and monitoring.

    摘要： Vehicle occupancy detection involves projecting modulated light onto an occupant from a light source outside of a vehicle. Reflections of the light source are received at a detector located outside of the vehicle. Three-dimensional data is determined based on a time-of-flight of the reflections, and the occupant is detected based on the three-dimensional data.
