Abstract
A light detection and ranging (lidar) system for a vehicle may include an input optical path, a first optical path, a plurality of second optical paths, a first optical amplifier, and a plurality of second optical amplifiers. The input optical path may be configured to receive a beam from a laser source. The first optical path and the plurality of second optical paths may be respectively branched from the input optical path. The first optical amplifier may be coupled to the first optical path and configured to output a local oscillator (LO) signal. The plurality of second optical amplifiers may be respectively coupled to the plurality of second optical paths, one of the plurality of second optical amplifiers being selectively turned on to modulate the beam received through a second optical path and output a modulated optical signal of the beam.
