Abstract: 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.

Abstract: An apparatus determines a cursor position (116) in an illumination field (110) of a projector. An obstruction (112) is detected in the illumination field. The cursor position is determined as the point on the obstruction furthest from where the obstruction crosses a border of the illumination field.

Abstract: A scanning projector (100) includes a mirror (142) that scans in two dimensions. The scanning mirror oscillates at a resonant frequency on a fast-scan axis, and is phase locked to an incoming frame rate on a slow-scan axis. An interpolation component (104) interpolates pixel intensity data from adjacent pixels based on the position of the mirror when a pixel clock arrives. Incoming video data is stored in a buffer. Less than a complete frame of video data may be stored in the buffer.

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: A scanning beam projection system (100) includes a scanning mirror (116) having a fast-scan axis and a slow-scan axis. Movement on the slow-scan axis is controlled by a slow-scan scanning mirror control system (130). The control system receives position information describing angular displacement of the mirror. An outer loop of the control system operates in the frequency domain and determines harmonic drive coefficients for a scanning mirror drive signal. An inner loop of the control system operates in the time domain and compensates for a scanning mirror resonant vibration mode at a frequency within the frequency band occupied by the harmonic drive coefficients.

Abstract: 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.
