Abstract

A three-dimensional scanning LiDAR based on one-dimensional optical phased arrays comprises a transmitting end, a coherent receiving end and an incoherent receiving end, wherein the transmitting end, the coherent receiving end and the incoherent receiving end are all one-dimensional arrays. A phase control complexity of the three-dimensional scanning phased array is reduced, and a tunable laser with high cost and a grating array antenna with large crosstalk are avoided. The LiDAR provides pure solid-state three-dimensional scanning in speed and integration level and is highly practical.
