Abstract: A lidar sensor assembly includes a plurality of light sources configured to generate light and a plurality of photodetectors for detecting the light potentially reflected off of objects in a field of view. Each of the photodetectors is associated with and configured to receive the light generated by one of the plurality of light sources. A generally transparent cover is disposed between (a) at least one of plurality of light sources and the plurality of photodetectors and (b) the field of view. The assembly further includes a processor in communication with the plurality of light sources and the plurality of photodetectors. The processor is configured to receive signals from the plurality of photodetectors. The processor is further configured to determine whether a blockage of the generally transparent cover exists based at least partially on the signals from the plurality of photodetectors.

Abstract: A Lidar system includes an array of photodetectors. The system includes a beam-steering device and a light emitter aimed at the beam-steering device. The beam-steering device is designed to aim light from the light emitter into a field of illumination positioned to be detected by a segment of the array of photodetectors. The segment is smaller than the array. The system includes a computer having a processor and memory storing instructions executable by the processor to adjust the aim of the beam-steering device to move the field of illumination relative to the array of photodetectors.

Abstract: A system includes photodetectors each having a field of view and reflectors each respectively aimed at one of the fields of view. A beam-steering device is movable to different positions aimed at the different reflectors. A light emitter is aimed at the beam-steering device. The beam-steering device alternates aim between the reflectors to selectively illuminate the different fields of view.

Abstract: A lidar sensor assembly includes a first detector array having a plurality of light sensitive detectors each configured to receive light reflected from an object and produce an electrical signal in response to receiving the light. The lidar sensor assembly also includes a second detector array having a plurality of detectors configured to receive light reflected from an object and produce an electrical signal in response to receiving the light. A readout integrated circuit (“ROIC”) is bonded to the first detector array and the second detector array. A gap is formed between the first detector array and the second detector array.

Abstract: A method for operating a ground-based anti-aircraft system includes providing a group of main system components containing a sensor system, a tactical operation control and an effector system. Combat target sensor data are passed from the sensor system to the tactical operation control, processed therein and passed in processed form from the tactical operation control to the effector system, using the data to combat the target. A central integration module having a converter unit and a central data distributor allows differently constructed main system components to be connected. Data from all main system components are routed to the central data distributor by the converter unit and converted therein from component protocol into system-internal data protocol, and passed from the central data distributor to one or more main system components, through the converter unit, converting the distributed data back from system-internal data protocol into component protocol.

Abstract: A number of ladar sensors, visible cameras, and traffic signal lights are mounted within a traffic control zone, and a local traffic controller is provided to ensure safety and provide optimum traffic flow for vehicular and pedestrian traffic by combining the inputs from the ladar sensors and visible cameras and detecting the type of traffic, the intended path, and then controlling the signal lights dynamically. The local traffic controller also maintains a local traffic database, and communicates via duplex radio link with similarly equipped vehicles to effect an additional control capability. A regional traffic controller communicates with the local traffic controller to provide control and optimal traffic flow within a district control zone, and maintains a district traffic database.
