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 list frames. Each defined shot list frame can identify various coordinates in the field of view that are to be targeted by a ladar pulses for a given ladar frame. 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 list frames should be selected for a given frame of ladar data.

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 various embodiment 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： Systems and methods are disclosed where a ladar system synthetically fills a ladar frame. A ladar transmitter can employ compressive sensing to interrogate a subset of range points in a field of view. Returns from this subset of range points correspond to a sparse ladar frame, and interpolation can be performed on these returns to synthetically fill the ladar frame.

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 control setting for use by a ladar system camera.

摘要： Disclosed herein is a ladar system that includes a ladar transmitter, ladar receiver, and camera, where the camera that is co-bore sited with the ladar receiver, the camera configured to generate image data corresponding to a field of view for the ladar receiver. In an example embodiment, a mirror can be included in the optical path between a lens and photodetector in the ladar receiver, where the mirror (1) directs light within the light from the lens that corresponds to a first light spectrum in a first direction for reception by the camera and (2) directs light within the light from the lens that corresponds to a second light spectrum in a second direction for reception by the photodetector, wherein the second light spectrum includes ladar pulse reflections for processing by the ladar system.

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.
