A Light Detection and Ranging (LIDAR) detector circuit includes a memory device comprising a first memory and a second memory, and at least one control circuit. The at least one control circuit is configured to execute first memory storage operations to store data indicated by detection signals received from one or more photodetector elements in the first memory during a first portion of a time between pulses of an emitter signal output from a LIDAR emitter element, and to execute second memory storage operations to include the data, which was stored in the first memory, in the second memory during a second portion of the time between the pulses of the emitter signal. Related devices and methods of operation are also discussed.

Pipelined histogram pixel

A Light Detection and Ranging (lidar) system, includes an emitter configured to emit a plurality of optical signals, a detector configured to be activated to detect one of the optical signals in light that is incident on the detector and to provide count data corresponding to the one of the optical signals that were detected, a plurality of storage memory locations configured to store the count data therein, and a control circuit configured to change a location at which the count data is stored from a first storage memory location to a second storage memory location based on an elapsed time duration from an emission of the one of the optical signals.

Strobing flash lidar with full frame utilization

A digital filtering algorithm preprocesses couplet defects prior to their being operated on by a main filtering algorithm that focuses on singlet defects. The preprocessing involves the replacement of one of the defective pixel values in the couplet with a pixel value that is known to be non-defective. In preferred embodiments, the selection of the pixel value in the couplet to be replaced is customized depending on the direction of scanning of the pixel array, and can take into account edge effects of border pixels.
