Abstract: A scanning mirror resonates on a first axis and moves on a second axis at a frequency dictated by a sync signal. The period of movement on the second axis is not necessarily an integer multiple of the period of movement on the first axis. A drive circuit excites movement of the mirror. The drive circuit adds a position offset to the signal that excites movement on the second axis. The position offset is capable of causing the resonant movement on the first axis to scan a substantially identical trajectory for at least a portion of each period on the second axis.

Abstract: Briefly, in accordance with one or more embodiments, a MEMS scanned beam projector includes a light source to emit a light beam, a scanning platform to redirect the light beam impinging on the platform, and a display controller to control the light source and the scanning platform to cause the scanning platform to scan the light beam in a vertical direction and a horizontal direction in a scan pattern to project an image onto a projection surface. The display controller is configured to correct for image distortion in the projected image by providing a compensated drive signal to the scanning platform to compensate for the image distortion.

Abstract: A scanning projector includes one or more scanning mirrors that reflect a light beam to create an image. The beam is created by multiple laser light sources, at least two of which create light at substantially the same color. The multiple laser light sources are used alternately to illuminate successive pixels, lines, and/or frames. Speckle reduction is achieved because of spatial overlap of the light beams produced by the multiple laser light sources.

Abstract: A light detection and ranging system includes synchronously scanning transmit and receive mirrors that scan a pulsed fanned laser beam in two dimensions. Imaging optics image a receive aperture onto an arrayed receiver that includes a plurality of light sensitive devices. Adaptive methods dynamically modify the size and location of the field of view as well as laser pulse properties in response to internal and external sensors data.

Abstract: A light detection and ranging system includes synchronously scanning transmit and receive mirrors that scan a pulsed fanned laser beam in two dimensions. Imaging optics image a receive aperture onto an arrayed receiver that includes a plurality of light sensitive devices. A phase offset may be injected into a scanning trajectory to mitigate effects of interfering light sources.

Abstract: A light detection and ranging system modulates laser light pulses with a channel signature to encode transmitted pulses with channel information. The modulated laser light pulses may be scanned into a field of view. Received reflections not modulated with the same channel signature are rejected. Multiple light pulses of different wavelengths may be similarly or differently modulated.

Abstract: A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.
