    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: 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.

    Abstract: A LIDAR system may include a processor configured to control a LIDAR light source in a manner enabling light flux to vary over scans of a field of view (FOV). The FOV may include foreground and background areas. The processor may be further configured to receive from a detector input signals indicative of light reflected from the FOV. A representation of a portion of the FOV associated with pixels may be constructible from the input signals associated with a first pixel that covers a portion of the foreground area, a second pixel that covers a portion of the foreground area and a portion of the background area, and a third pixel that covers a portion of the background area. The processor may be further configured to determine a distance to a first object located in the foreground area and a distance to a second object located in the background area.

    Abstract: A LIDAR system may include at least one processor configured to control at least one light source for emitting a light flux. The at least one processor may also be configured to control a light deflector to deflect light from the at least one light source in order to scan a field of view. The at least one processor may further be configured to detect an object within the field of view based on first reflections from the field of view received by at least one sensor. The at least one processor may also be configured to determine a first position of the light deflector based on second reflections from the field of view received by a plurality of detector cells, and control a repositioning of the light deflector to a second position based on the first position of the light deflector and an intended illumination location.

    Abstract: In some embodiments, a LIDAR system may include at least one processor configured to control at least one light source for projecting light toward a field of view and receive from at least one first sensor first signals associated with light projected by the at least one light source and reflected from an object in the field of view, wherein the light impinging on the at least one first sensor is in a form of a light spot having an outer boundary. The processor may further be configured to receive from at least one second sensor second signals associated with light noise, wherein the at least one second sensor is located outside the outer boundary; determine, based on the second signals received from the at least one second sensor, an indicator of a magnitude of the light noise; and determine, based on the indicator the first signals received from the at least one first sensor and, a distance to the object.
