    Abstract: A photodiode-based detection module may include at least one photodiode for detecting light. The photodiode-based detection module may also include a sensitivity damper configured to temporarily reduce the sensitivity of the at least one photodiode. The photodiode-based detection module may further include a controller configured to trigger the sensitivity damper to reduce a sensitivity of the at least one photodiode to less than a nominal sensitivity threshold.

    Abstract: Provided herein are an oscillator assembly including a stator, a rotor and at least one rotor magnet disposed on the rotor. The rotor magnet configured to move with the rotor between a first terminal point and a second terminal point. The assembly includes a counter-rotating mass (CRM) rotatably and elastically mounted on the stator, wherein the rotor is rotatably mounted on the CRM. The CRM including a first energy conversion element (ECE) disposed on the CRM, wherein the first ECE is configured to transfer torque from the rotor to the CRM, thereby causing rotation of the CRM and at least a second ECE disposed on the CRM, wherein the second ECE is configured to transfer torque from the rotor to the CRM, thereby causing rotation of the CRM.

    Abstract: A LIDAR system is disclosed. The system may include a laser light projection system that may simultaneously provide at least two laser light beams. The system may also include an optical system, including one or more deflectors to project the at least two laser light beams toward a field of view of the LIDAR system. Each of the laser light beams may have an energy density below an eye safe level. However, a total combined energy density of the laser light beams may exceed an eye safe level. The laser light beams may be projected from the deflector are spaced apart from one another by an angular spacing ranging from 2.5 mrad to 6 mrad.

    Abstract: A time-of-flight (TOF) optical sensor may include a controller, a sensing array, and a readout unit. The sensing array may include a plurality of sensing cells. The readout unit may include a plurality of readout TOF modules. The number of the plurality of readout TOF modules may be less than the number of the plurality of sensing cells. The controller may be configured to trigger a connection of a first sensing cell of the plurality of sensing cells to a first readout TOF module of the plurality of readout TOF modules at a first time during a sampling period, thereby enabling the first readout TOF module to provide a first measurement of a change in output of the first sensing cell.

    Abstract: Systems and methods are disclosed for a LIDAR system with a mirror housing and a window. The LIDAR system may include a light deflector, a mirror housing encasing the light deflector comprising a window for transmitting light between the light deflector and an exterior of the mirror housing, and a sensor positioned outside the mirror housing for detecting light signals from an environment of the LIDAR system. The light signals may propagate from the environment through the window to the light deflector, and from the light deflector through the window to the sensor. The window may be configured such that light arriving from outside of a field of view of the LIDAR system is deflected by the window away from the sensor. The LIDAR system may also include a processor for processing the light signals detected by the sensor to determine a distance to an object in the environment of the LIDAR system.

    Abstract: A LIDAR system for detecting a vehicle may include a processor configured to: scan a field of view (FOV) by controlling movement of at least one deflector at which at least one light source is directed; receive from at least one sensor signals indicative of light reflected from a particular object in the FOV; detect, based on time of flight in the received signals, portions of the particular object in the FOV that are similarly spaced from the light source; determine, based on the detected portions, at least a first portion having a first reflectivity corresponding to a license plate, and at least two additional spaced-apart portions corresponding to locations on the particular object other than a location of the first portion; and based on a spatial relationship and a reflectivity relationship between the first portion and the at least two additional portions, classify the particular object as a vehicle.
