Abstract: A method for reducing interference in a light ranging and detection (LiDAR) system is provided. The method comprises receiving noise by a light detector of the LiDAR system, determining whether the received noise is caused by interference from at least one other LiDAR system, and in accordance with a determination that the detected noise is caused by interference from the at least one other LiDAR system, de-synchronizing the LiDAR system with the at least one other LiDAR system.

Abstract: A method for tracking zero-angle position shift of a moveable mirror used in a LiDAR system is provided. The method comprises obtaining a first dataset based on a first intensity map. The first intensity map is associated with internal reflection pulses of a frame scanned by the LiDAR system. The frame comprises a plurality of scan positions. The internal reflection pulses are formed by scattering or reflecting one or more transmission light pulses at positions internal to a housing of the LiDAR system. The first dataset is a calibration dataset comprising representative intensity values and corresponding positions in the frame. The method further comprises obtaining a second intensity map of another frame at a subsequent time and obtaining a second dataset based on the second intensity map. The method further comprises determining the zero-angle position shift of the moveable mirror based on the first dataset and the second dataset.

Abstract: A system and method for reducing electromagnetic interference comprises generating a first voltage signal based on a settling time of a first electrode, a slew rate of a signal generator, and a harmonic parameter, and driving the first electrode with the first voltage signal. The first voltage signal may be one of a capacitive sensing signal, display update signal, a transmission signal, and a selection signal. Further, a processing system may be configured to operate in one of an absolute capacitive sensing mode and a transcapacitive sensing mode. In an absolute capacitive sensing mode, the processing system is configured to receive a resulting signal with the first electrode, and determine a measurement of a change in capacitive coupling of the first electrode based on the resulting signal.
