Embodiments discussed herein refer to LiDAR systems that accurately observe objects that are relatively close and objects that are relatively far using systems and methods that employ a variable time interval between successive laser pulses and one or more filters.

LiDAR detection systems and methods with high repetition rate to observe far objects

A light detection and ranging (LiDAR) scanning system is provided. The system comprises a light steering device; a galvanometer mirror controllable to oscillate between two angular positions; and a plurality of transmitter channels configured to direct light to the galvanometer mirror. The plurality of transmitter channels are separated by an angular channel spacing from one another. The system further comprises a control device. Inside an end-of-travel region, the control device controls the galvanometer mirror to move based on a first mirror movement profile. Outside the end-of-travel region, the control device controls the galvanometer mirror to move based on a second mirror movement profile. The second mirror movement profile is different from the first mirror-movement profile. Movement of the galvanometer mirror based on the first mirror movement profile facilitates minimizing instances of scanlines corresponding to the end-of-travel region having a pitch exceeding a first target pitch.
