    Abstract: An integrated photonics module includes at least one light source and a MEMS scanner coupled to and held in alignment by an optical frame configured for mounting to a host system. According to some embodiments, the integrated photonics module may include a plurality of light sources and a beam combiner coupled to the optical frame. According to some embodiments, the integrated photonics module includes a selective fold mirror configured to direct at least a portion of emitted light toward the MEMS scanner in a normal direction and pass scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.

    Abstract: Aspects of the subject matter described herein relate to improving images obtained from an image-acquiring system (e.g., such as a scanned laser beam camera, a scanned laser imager, or other image-acquiring system). In certain aspects, an image frame is obtained from which a histogram is created. Characteristics of the image are determined based on the histogram. These characteristics are used to make an image quality judgment regarding the image. This judgment is then used to adjust parameters in the image-acquiring system for obtaining a subsequent frame. Parameters may be adjusted even if the image is judged as normal. Other aspects are described in the specification.

    Abstract: A scanned beam imager or laser scanner is operable to scan an object moving through its field-of-view. The system may include means for detecting direction and/or speed of the object. The velocity detection means may include sensors, an interface for receiving velocity information from other system elements, or image analysis that examines the skew, stretch, or compression in images. Responsive to object movement direction and speed, the scanned beam imager may alter its pixel capture rate and/or its scan rate to compensate. Alternatively or in combination, the imager may perform software-based image motion compensation. In some embodiments, the system may allow the image capture region to pace objects moving rapidly through its field-of-view.

    Abstract: An aperture plate includes an opening and a surface adjacent to the opening. The opening passes electromagnetic energy such as light to a reflector that is aligned with the opening and that directs the electromagnetic energy to a location. The surface reflects incident electromagnetic energy away from the location in a direction that is outside of the range of directions. Such an aperture plate insures that electromagnetic energy, e.g., light, strikes only the desired portions of the reflector, and that peripheral light that is outside of the aperture opening is reflected away from the location, e.g., display screen, toward which the reflector directs the electromagnetic energy. Furthermore, because such an aperture plate is mounted near the reflector, the alignment tolerances are typically less stringent than for an aperture plate mounted near the energy source.

    Abstract: A scanner such as a bar-code scanner includes a scan-beam generator, a beam reflector having a first magnet, and a beam-sweep mechanism having a second magnet. The beam-sweep mechanism causes the reflector to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet with the second magnet. In one example, attraction between the magnets holds the reflector steady in a non-sweep position. Conversely, in a sweep position, repulsion between the magnets causes the reflector to oscillate and sweep the scan beam across a target such as a bar-code symbol. Because it does not include a motor for rotating a beam-sweep mirror, the scanner is often smaller and uses less electrical energy than motorized bar-code scanners.

    Abstract translation: 诸如条形码扫描器的扫描器包括扫描光束发生器，具有第一磁体的光束反射器和具有第二磁体的光束扫描机构。 光束扫描机构使得反射器通过用第二磁体施加在第一磁体上的力而将扫描光束扫过诸如条形码符号的目标。 在一个示例中，磁体之间的吸引力将反射器保持在非扫掠位置。 相反，在扫掠位置，磁体之间的排斥使得反射器振荡并扫过扫描光束穿过诸如条形码符号的目标。 因为它不包括用于旋转光束扫描镜的电机，所以扫描器通常较小并且比电动条形码扫描器使用更少的电能。
