Abstract
An integrated photonics module may include a selective fold mirror configured to pass at least a portion of emitted light toward the MEMS scanner and reflect 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.
