摘要： A scanned light display system includes a light source operable to emit light and a curved mirror positioned to receive at least a portion of the light. The curved mirror is configured to substantially collimate the received light. The substantially collimated light is scanned to form an image by moving at least one of the light source and the curved mirror relative to each other. Alternatively, the scanned light display system includes a light source operable to emit light, a curved mirror positioned to receive some of the light, and an optical element positioned to receive light reflected from the curved mirror. The optical element is configured to substantially collimate the reflected light. The substantially collimated light is scanned to form an image by moving at least one of the light source, the curved mirror, and the optical element. Scanning mirror assemblies and methods of making are also disclosed.

摘要： 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.

摘要： The temperature of a laser diode changes in response to video content across a line of a displayed image, and the radiance changes as a function of temperature. An adaptive model estimates the temperature of the laser diode based on prior drive current values. For each displayed pixel, diode drive current is determined from the estimated diode temperature and a desired radiance value. A feedback circuit periodically measures the actual temperature and updates the adaptive model.

摘要： A scan assembly includes an emitter array containing a plurality of optical emitters. Each optical emitter generates a corresponding image beam and the scan assembly scans the image beams in a plurality of overlapping display zones. The overlap of adjacent image display zones forms blending zones and the scan assembly can modulate the intensities of the image beams as a function of the position of the image beams in the blending zones. This modulation for a given blending zone may be a linearly increasing intensity of a first image beam and a linearly decreasing intensity of a second image beam.
