Abstract: The present disclosure relates to a light detection and ranging (LIDAR) sensor comprising a detector configured to generate a first detector signal at a first delay time following an emission of a first light pulse and to generate at least one second detector signal at the first delay time following an emission of at least a second light pulse; and a processor configured to generate a combined signal for the first delay time based on a combination of the first detector signal and the at least one second detector signal. Depending on the type of combination, the combined signal can be used for interference detection or mitigation.

Abstract: A MEMS device includes a body pivoting around a pivot axis, a support, and a suspension structure mechanically coupling the body to the support. The suspension structure includes a torsion element defining the pivot axis, and first and second spring elements extending with an angle relative to the pivot axis on opposing sides of the torsion element so that a distance between at least portions of the first and second spring elements is changing in the direction of the pivot axis. The extension of the first and second spring elements in the direction of the pivot axis is larger than the extension of the torsion element in the direction of the pivot axis.

Abstract: Systems and methods are provided for monitoring properties of a microelectromechanical systems (MEMS) oscillating structure. A system includes a MEMS oscillating structure configured as a non-linear resonator to oscillate about a rotation axis; a driver configured to generate a driving force for driving the MEMS oscillating structure about the rotation axis according to an operating response curve during which the MEMS oscillating structure is in resonance, the driver further configured to decrease the driving force when the MEMS oscillating structure is at a predefined tilt angle to induce an oscillation decay of the MEMS oscillating structure; a measurement circuit configured to measure an oscillation frequency and a tilt angle amplitude of the MEMS oscillating structure during a decay period; and processing circuitry configured to determine at least one characteristic of the MEMS oscillating structure based on at least one of the measured oscillation frequency and the measured tilt angle amplitude.

Abstract: A Light Detection and Ranging (LIDAR) system includes a LIDAR transmitter and a controller. The LIDAR transmitter, driven by the controller, scans a field of view with laser beams, where each laser beam has a beam width that, when projected into a field of view, coincides with an angle region of the field of view. The LIDAR transmitter transmits a first plurality of laser beams in a first scan, where a first plurality of angle regions covered by the first plurality of laser beams are mutually exclusive of each other. The LIDAR transmitter transmits a second plurality of laser beams in a second scan, where a second plurality of angle regions covered by the second plurality of laser beams are mutually exclusive of each other. Each of the second plurality of angle regions partially overlaps with a different corresponding one of the first plurality of angle regions.

Abstract: A light detection and ranging (LIDAR) system is provided. The LIDAR system comprises at least two lasers configured to emit aligned beams of light and a mirror configured to deflect the beams of light emitted by the lasers. The mirror is supported to be pivotable with respect to an axis of the mirror so as to allow the beams of light to scan a field of view of the LIDAR system. The LIDAR system further comprises a driver configured to drive the mirror into oscillations and a controller. The controller is configured to control at least one laser so as to selectively change a size of the field of view and/or to control the driver so as to selectively change the size of the field of view.
