    Abstract: An autonomous vehicle having a LIDAR system that scans a field of view is described herein. With more specificity, a computing system of the autonomous vehicle defines a region of interest in the field of view for a scan of the field of view by the LIDAR system. The region of interest is a portion of the field of view. Based on the region of interest, the computing system transmits a control signal to the LIDAR system that causes the LIDAR system to emit first light pulses with a first intensity within the region of interest during the scan and second light pulses with a second intensity outside the region of interest during the scan. The first intensity is different from the second intensity to provide different ranges for distance measurements inside and outside the region of interest.

    Abstract: A method for detecting violation of a driving-related law includes producing, by at least one camera, at least one image of a vehicle. The method includes analyzing, by an analysis engine, the at least one image. The analysis engine identifies, based on analyzing the at least one image, a physical position of a driver of the vehicle within the vehicle and identifies a direction of a gaze of the driver. The analysis engine determines that at least one of the physical position of the driver within the vehicle and the direction of the gaze of the driver are associated with a violation of a driving-related law. The method includes transmitting, by a citation management component, a notification of the association between the at least one of the physical position of the driver and the direction of the gaze of the driver and the violation, based upon the determination.

    Abstract: A method for detecting objects using a LIDAR system may include controlling a light emission assembly comprising a light source in a manner enabling spatial light modulation to a field of view (FOV) of the LIDAR system to vary during different flash light emissions of the light emission assembly. The method may also include controlling a sensor to detect first reflection signals indicative of reflections of first flash light emissions from objects in the FOV. The method may further include determining a nonuniform spatial light modulation for the light emission assembly based on at least one of the first reflection signals. The method may also include instructing the light emission assembly to emit to the FOV a second flash light emission in accordance with the nonuniform spatial light modulation, and detecting an object in the FOV based on second reflection signals of the second flash light emission.

    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.
