    摘要： An arrangement for improving performance of a sensor operative for collecting light from a target to generate a data signal in a presence of ambient light, includes a sample and hold circuit for operating the sensor during a sampling time period in which the sensor only collects the ambient light to generate an ambient signal, and during a holding time period in which the sensor collects both the ambient light and the light from the target to generate a composite signal comprised of the ambient signal and the data signal; and a subtracting circuit operative for subtracting the ambient signal from the composite signal to produce the data signal as an output.

    摘要： A lightweight, compact image projection module, especially for mounting in a housing having a light-transmissive window, is operative for causing selected pixels in a raster pattern to be illuminated to produce an image of high resolution of VGA quality in color. The pixels are rendered symmetrical in cross-section by aligning a narrow dimension of a beam spot of a laser beam along scan lines of the raster pattern.

    摘要： A method and apparatus are provided to controllably reduce power of a laser projection display (LPD) in response to detecting a variation in a viewing surface. During the operation of the LPD, a controller 142 monitors laser light being reflected from the viewing surface. Since the controller 142 “knows” the amount of power that the LPD is being instructed to deliver, it may compare the known power to the reflected laser light to determine if a foreign object may be in the path of the laser light, and therefore, affecting the magnitude of the laser light. The controller 142 responds to detecting such an event by reducing power to the lasers.
