Devices, systems, and methods are provided for reducing interference of light detection and ranging (LIDAR) emissions. A vehicle may identify location information associated with a location of the vehicle. The vehicle may select, based on the location information, a modulation code associated with a LIDAR photodiode of the vehicle. The vehicle may emit, using the LIDAR photodiode, one or more LIDAR pulses based on the modulation code.

Reducing coexistence interference for light detection and ranging

Systems/methods for operating a LiDAR system. The methods comprise: receiving a waveform representing light which was reflected off of a surface of an object; generating timestamp values for photon detection events triggered by pulses in the waveform; generating a count histogram of the timestamp values; inferring a trials histogram from the count histogram (the trials histogram representing a number of times a photodetector of the LiDAR system was available during reception of the waveform); generating an estimated range distance from the LiDAR system to the at least one object and an estimated intensity value for a given pulse of the waveform, based on results from analyzing the count histogram and the trials histogram; determining a position using the estimated range distance from the LiDAR system to the at least one object; and producing a LiDAR dataset comprising a data point defined by the position and the estimated intensity value.

Systems and methods for analyzing waveforms using pulse shape information

Devices, systems, and methods are provided for compressive sensing using photodiode data. A device may identify light detecting and ranging (LIDAR) data detected by a sensor, the LIDAR data including a first time-of-flight (ToF) and a second ToF. The device may generate, based on the first ToF, a first frequency value. The device may generate, based on the second ToF, a second frequency value. The device may generate, based on the first value, a first sinusoid. The device may generate, based on the second value, a second sinusoid. The device may generate, based on the first sinusoid and the second sinusoid, a compressed signal in a domain incoherent with the time domain. The device may extract range information based on the compressed signal, and may control operation of a vehicle based on the range information.

Compressive sensing for photodiode data

A single photon counting sensor array includes one or more emitters configured to emit a plurality of pulses of energy, and a detector array comprising a plurality of pixels. Each pixel includes one or more detectors, a plurality of which are configured to receive reflected pulses of energy that were emitted by the one or more emitters. A mask material is positioned to cover some but not all of the detectors of the plurality of pixels to yield blocked pixels and unblocked pixels so that each blocked pixel is prevented from detecting the reflected pulses of energy and therefore only detects intrinsic noise.
