    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 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.

    Abstract: In a non-collinear type acousto-optic tunable filter, the incident angle of a source light beam L.sub.1 radiated from a light source 6 onto an acoustic medium 1 is set at an equivalence incident angle for which the wavelength .lambda..sub.i of the diffracted ordinary ray L.sub.3 and the wavelength .lambda..sub.i ' of the diffracted extraordinary ray L.sub.4 become approximately identical. Further, the diffracted ordinary ray L.sub.3 and the diffracted extraordinary ray L.sub.4 of the approximately identical wavelength are superposed, and the intensity of the superposed ray is detected. Consequently, spectrometry is performed based on the superposed diffracted ray having twice the intensity and a very sharp waveform, so that accurate spectroscopy can be made possible even if the intensity of the source light beam is low.

According to one embodiment, the MEMS device includes drive electronics operable to generate a drive signal that causes the scanner to oscillate at an operational frequency about the at least one rotation axis. The drive signal has a drive frequency selected to be about equal to the characteristic resonant frequency or a sub-harmonic frequency of the characteristic resonant frequency. According to another embodiment, the drive electronics are operable to generate a drive signal having a plurality of drive-signal pulses that moves the scanner at an operational frequency and sensing electronics are operable to sense a position of the scanner only when the drive-signal pulses of the drive signal are not being transmitted by the drive electronics. The MEMS device embodiments may be incorporated in scanned beam imagers, endoscopes, and displays.

    Abstract: A method comprises applying a first delay to a first signal that is ahead of a second signal in a series of signals and determining a first number of delay units that provides the first delay to change an order between the delayed first signal and the second signal that has a phase difference with the first signal. The method further comprises determining a similar number for any other pair of signals in the series of signals that have the phase difference. The method further comprises determining a maximum and a minimum from the obtained numbers and determining linearity of the seriels of signals based on a difference between the maximum and the minimum.
