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. Scanning mirror offsets may be applied to modify a fan angle of the pulsed fanned laser beam. Adaptive methods dynamically modify the size and location of the field of view, laser pulse properties, and/or fan angle in response to internal and external sensors data.

Abstract: A light detection and ranging system includes multiple scanning mirror assemblies to increase a receive aperture. The multiple scanning mirror assemblies are controlled to mimic the operation of one large scanning mirror. The multiple scanning mirror assemblies may be arranged in one-dimensional arrays or two-dimensional arrays. Two arrays of scanning mirror assemblies provide for scanning in two dimensions.

Abstract: A projection system emits light pulses in a field of view and measures properties of reflections. Properties may include time of flight and return amplitude. Foreground objects and background surfaces are distinguished, distances between foreground objects and background surfaces are determined based on reflections that are occluded by the foreground objects and other properties of the projection system.

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 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.

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: An eye-safe light detection and ranging system includes a virtual protective housing. A short range pulse is emitted at every measurement point in a field of view before conditionally emitting a long range pulse. Short range pulses result in accessible emissions that are eye-safe at short distances and long range pulses result in accessible emissions that are eye-safe at longer distances.
