A Light Detection and Ranging (LiDAR) target signal selection apparatus may include a processor configured to estimate a target signal among signals of a current frame N by use of a determined target signal of a previous frame N−1 among N LiDAR receiving signals, and to determine the estimated target signal based on deviations of previous frames 1 to N−1; and a storage configured to store data and algorithms driven by the processor.

Embodiments of the disclosure provide a method for designing an optical scanning mirror. The method may include receiving, by a communication interface, a set of design parameters of the scanning mirror. The method may also include simulating scanning mirror oscillation, by at least one processor, based on the set of design parameters using a computer model. In certain aspects, the computer model may include a lookup table that correlates electrostatic force applied to a sample scanning mirror and angular displacement in the sample scanning mirror caused by the electrostatic force. The method may further include generating, by the at least one processor, mirror oscillation data as an output of the computer model for designing the scanning mirror. The mirror oscillation data may include a correlation of drive frequency, angular displacement, and time.

A lidar receiver can employ multiple processors to distribute the workload of processing returns from laser pulse shots. Activation/deactivation times of pixel sets that are used by the lidar receiver to sense returns can be used to define which samples in a return buffer will be used for processing to detect each return, and multiple processors can share the workload of processing these samples in an effort to improve the latency of return detection
