Abstract: An optical scanner including micro-electromechanical system phased-arrays suitable for use in a LiDAR system, and methods of operating the same are described. Generally, the scanner includes an optical transmitter having first phased-arrays to receive light from a light source, form a swath of illumination in a far field scene and to modulate phases of the light to sweep or steer the swath over the scene in two-dimensions (2D). An optical receiver in the scanner includes second phased-arrays to receive light from the far field scene and direct at least some of the light onto a detector. The second phased-arrays are configured to de-scan the received light by directing light reflected from the far field scene onto the detector while rejecting background light. In one embodiment the second phased-arrays direct light from a slice of the far field scene onto a 1D detector array.

Abstract: Techniques for separating an image into a forward sweeping image and a backward sweeping image are disclosed. A lookup table maps MEMS projection positions on a display with corresponding pixel positions in an image generated by a camera facing the display. The lookup table is used to associate a first set of pixel positions in the image with a forward scanning sweep of the MEMS system. The lookup table is also used to associate a second set of pixel positions in the image with a backward scanning sweep of the MEMS system. The first and second sets of pixel positions are used to generate the forward sweeping image and the backward sweeping image, respectively. These images can then be used to calibrate the MEMS system to compensate for bi-phase.

Abstract: A direct retinal projector may include a gaze tracking system that tracks position of a subject's pupil and automatically adjusts projection of a scanned light field so that the light field enters the pupil. A control loop adjusts a scanning mirror to substantially center an IR beam on a position sensing detector (PSD). In so doing, the scanning mirror is correctly positioned so that the scanned light field from the projector enters the subject's pupil. In addition, a direct retinal projector may include an adjustable focusing element that adjusts focus of a combined light beam generated by a projector as the light beam is scanned to an ellipsoid mirror that reflects the light beam to the subject's pupil. The focusing of the scanned beam may be adjusted as the beam is scanned across the azimuth angle of the curved ellipsoid mirror.
