Abstract

To obtain high ranging resolution and to record full waveform signals, full waveform LiDAR requires short pulse width laser sources, high bandwidth sensors, high bandwidth A/Ds, and large on-board memories. To relax these requirements, temporal super-resolution is studied in this paper. In temporal super-resolution, the reflected beam is split into several branches, and then transpose through different distances before collected by detectors. The minimum distance difference among branches determines the system resolution. To reduce the number of measurements, compressive sensing idea is further used in temporal super-resolution LiDAR.
