    Abstract: A pulsed laser diode driver may include at least one low side switching circuit connected to at least one laser diode. The at least one laser diode may generate at least one light pulse. The low side switching circuit may include an input for receiving energy. The low side switching circuit may also include an inductor configured to store at least a portion of the received energy. Further, the low side switching circuit may include a trigger switch. The trigger switch may cause the inductor to store the portion of the received energy when the trigger switch is closed, and the trigger switch may cause the portion of the received energy stored in the inductor to be delivered to the at least one laser diode after the trigger switch is opened.

    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: An electrooptical system may include a processor programmed to control a light source to enable light flux to vary over a scan of a field-of-view using light from the light source. The FOV may be divided into a plurality of segments, which may include a first set of non-contiguous segments, and each of the non-contiguous segments included in the first set may be separated from other non-contiguous segments in the first set by at least one segment. The scanning of the field-of-view may include sequentially illuminating the non-contiguous segments, which may proceed such that, during illumination of a particular non-contiguous segment in the first set of non-contiguous segments, other segments in the plurality of segments are not be illuminated, and such that other segments in the plurality of segments are not be illuminated between the illuminations of the non-contiguous segments in the first set of non-contiguous segments.

    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.

    Abstract: A LIDAR system for use in a vehicle is provided. The LIDAR system may include at least one processor configured to control at least one light source for illuminating a field of view and scan a field of view by controlling movement of at least one deflector at which the at least one light source is directed. The at least one processor may also be configured to receive, from at least one sensor, reflections signals indicative of light reflected from an object in the field of view. The at least one processor may further be configured to detect at least one temporal distortion in the reflections signals, and determine from the at least one temporal distortion an angular orientation of at least a portion of the object.

    Abstract: A device includes an optical path and a beam profile redistributor arranged in the optical path to receive an input light beam. The beam profile redistributor is configured to convert the received input light beam so that at least one output light beam of the device includes, (i) in a near field and/or at the beam profile redistributor, a redistributed beam intensity profile compared to at least one further output light beam when the beam profile redistributor is not present, (ii) within a given measuring aperture at a position along the optical path in the near field, a lower output light power compared to the at least one further output light beam, and (iii) in a far field, at least substantially the same beam intensity profile compared to the at least one further output light beam. Other embodiments are also described.

    Abstract: A LIDAR system may have a laser emission unit configured to generate a plurality of laser beams. The LIDAR system may also have an optical system configured to transmit the plurality of laser beams from the laser emission unit to a common scanning unit. The common scanning unit may be configured to project the plurality of laser beams towards a first set of spaced apart locations of a field of view of the LIDAR system. The first set of spaced apart locations may be associated with a first plurality of parallel scan lines traversing the field of view. The common scanning unit may also be configured to simultaneously scan the field of view along the first plurality of scan lines by sequentially illuminating non-contiguous segments in a first set of non-contiguous segments of the field of view positioned along the first plurality of scan lines.
