    摘要： A scanned light display system includes a light emitter array having a plurality of light sources operable to emit diverging light and an array of collimating elements positioned so that each of the collimating elements receive at least a portion of the light emitted from a corresponding one of the light sources. Each of collimating elements is configured to substantially collimate the received light from at least one corresponding light source into respective beams. The scanned beam display is operable to scan the respective beams to provide an image to a viewer. The displayed image appears substantially fixed to a viewer as the viewer's eye moves relative to the array of collimating elements. In one embodiment, each of the collimating elements is a curved mirror. In other embodiments, each of the collimating elements includes at least one lens or a curved mirror/lens pair.

    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： A laser drive controller compensates for temperature-dependent effects of a temperature-sensitive laser. Temperature variations in the laser may be measured and/or predicted based on variable pulsed output. The controller may drive the laser to maintain temperature and/or to compensate for variations in temperature. The techniques may be applied to a laser scanner, scanned beam display, laser printer, laser camera, scanned beam imager, etc.

    摘要： Various embodiments of the present invention provide for systems and apparatuses directed toward using a contact lens and deflection optics to processes display information and non-display information. In one embodiment of the invention, a contact lens assembly is provided, comprising: a substrate including optical path optics and configured to receive a display information optical path emitted from a display and a non-display information optical path not emitted from the display. The optical path optics of the substrate is configured to be partially deflective such that the non-display information optical path is transmitted to a human visual system without deflection, and the display information optical path is transmitted to the human visual system with deflection.
