Abstract: Example implementations may relate to determining a strategy for a drop process associated with a light detection and ranging (LIDAR) device. In particular, the LIDAR device could emit light pulses and detect return light pulses, and could generate a set of data points representative of the detected return light pulses. The drop process could involve a computing system discarding data point(s) of the set and/or preventing emission of light pulse(s) by the LIDAR device. Accordingly, the computing system could detect a trigger to engage in the drop process, and may responsively (i) use information associated with the environment around the vehicle, operation of the vehicle, and/or operation of the LIDAR device as a basis to determine the strategy for the drop process, and (ii) engage in the drop process in accordance with the determined strategy.

Abstract: Computing devices, systems, and methods described in various embodiments herein may relate to a light detection and ranging (lidar) system. An example computing device could include a controller having at least one processor and at least one memory. The at least one processor is configured to execute program instructions stored in the at least one memory so as to carry out operations. The operations include receiving information identifying an environmental condition surrounding a vehicle, the environmental condition being at least one of fog, mist, snow, dust, or rain. The operations also include determining a range of interest within a field of view of the lidar system based on the received information. The operations also include adjusting at least one of: a return light detection time period, sampling rate, or filtering threshold, for at least a portion of the field of view based on the determined range of interest.

Abstract: One example method involves repeatedly scanning a range of angles in a field-of-view (FOV) of a light detection and ranging (LIDAR) device. The method also involves detecting a plurality of light pulses intercepted for each scan of the range of angles. The method also involves comparing a first scan of the range of angles with a second scan subsequent to the first scan. The method also involves detecting onset of a saturation recovery period of the light detector during the first scan or the second scan based on the comparison.

Abstract: The present disclosure relates to light detection and ranging (LIDAR) devices and related methods of their use. An example LIDAR device includes a transmitter configured to transmit one or more light pulses into an environment of the LIDAR device via a transmit optical path. The LIDAR device also includes a detector configured to detect a first portion of the one or more transmitted light pulses and a second portion of the one or more transmitted light pulses, such that the detector receives at a first time the first portion of the one or more transmitted light pulses via an internal optical path within the LIDAR device and receives at a second time the second portion of the one or more transmitted light pulses via reflection by one or more objects in the environment of the LIDAR device. The second time occurs after the first time.
