Abstract
Methods, apparatus, and systems related to light detection and ranging (LIDAR) are described. In one example aspect, a LIDAR apparatus includes a light emitter configured to generate, according to a first electrical pulse signal, a pulse light signal. The first electrical pulse signal comprises a first set of non-uniformly spaced pulses. The apparatus includes a receiver configured to convert returned light signals from the object into electrical signals and a filtering subsystem in communication with the receiver, configured to receive the electrical signals from the receiver and remove a point from a set of points representing at least a partial surface of the object as noise by determining whether there is a coherence between the point and corresponding neighboring points of the point along at least a first direction and a second direction of the set of points.
