Abstract
Lidar detection device based on a lens and an integrated beam transceiver, comprising a laser, a coupling fiber, a substrate, an input waveguide, a connection waveguide, a 1×N optical switch, a switch electrical interface, N switch output waveguides, N transceiving units, an off-chip processor and a lens, wherein N is a positive integer above 2. The invention can realize three-dimensional detection of a target, and the invention has the characteristics of two-dimensional beam steering independent of wavelength switching, low control complexity, low electric power consumption, receiving and emitting monolithic integration and high receiving efficiency, and being compatible with two laser ranging functions of ToF and FMCW.
