摘要： Disclosed herein are various embodiments of an adaptive ladar receiver and associated method whereby the active pixels in a photodetector array used for reception of ladar pulse returns can be adaptively controlled based at least in part on where the ladar pulses were targeted. Additional embodiments disclose improved imaging optics for use by the receiver and further adaptive control techniques for selecting which pixels of the photodetector array are used for sensing incident light.

摘要： A ladar system and related method are disclosed where a ladar transmitter transmits ladar pulses toward a plurality of range points, and a ladar receiver receives ladar returns from the range points, wherein the ladar receiver comprises a photo receiver. A sensor can be used to sense background light levels, and a control circuit can (1) measures the sensed background light levels and (2) provide frequency domain shuttering with respect to the photo receiver based on the measured background light levels.

摘要： Disclosed herein are examples of ladar systems and methods where data about a plurality of ladar returns from prior ladar pulse shots gets stored in a spatial index that associates ladar return data with corresponding locations in a coordinate space to which the ladar return data pertain. This spatial index can then be accessed by a processor to retrieve ladar return data for locations in the coordinate space that are near a range point to be targeted by the ladar system with a new ladar pulse shot. This nearby prior ladar return data can then be analyzed by the ladar system to help define a parameter value for use by the ladar system with respect to the new ladar pulse shot. Examples of such adaptively controlled parameter values can include shot energy, receiver parameters, shot selection, camera settings, and others.

摘要： Disclosed herein are a number of example embodiments that employ controllable delays between successive ladar pulses in order to discriminate between “own” ladar pulse reflections and “interfering” ladar pulses reflections by a receiver. Example embodiments include designs where a sparse delay sum circuit is used at the receiver and where a funnel filter is used at the receiver. Also, disclosed are techniques for selecting codes to use for the controllable delays as well as techniques for identifying and tracking interfering ladar pulses and their corresponding delay codes. The use of a ladar system with pulse deconfliction is also disclosed as part of an optical data communication system.

摘要： Systems and methods are disclosed for vehicle motion planning where a sensor, such as a ladar system, is used to detect threatening or anomalous conditions within the sensor's field of view so that priority warning data about such conditions can be inserted at low latency into the motion planning loop of a motion planning computer system for the vehicle. The ladar system can perform compressive sensing to target the field of view with a plurality of ladar pulses.

摘要： A ladar transmitter that transmits ladar pulses toward a plurality of range points in a field of view can be controlled to target range points based on any of a plurality of defined shot patterns. Each defined shot pattern can be instantiated to identify various coordinates in the field of view that are to be targeted by a ladar pulses. A processor can process data about the field of view such as range data and/or camera data to make selections as to which of the defined shot patterns should be selected over time.
