LiDAR DEVICE, LiDAR SYSTEM, AND MEASUREMENT METHOD USING LiDAR

摘要

[Problem] To suppress the deterioration of signal quality in an optical signal. [Solution] A LiDAR device comprises: a signal output means 20 for outputting a first electric signal in a first period, reducing the amplitude of the first electric signal outside the first period, and then outputting a second electric signal; a modulator 30 which outputs an optical signal modulated on the basis of the first electric signal or the second electric signal; and a control means 40 for applying, to the modulator 30, a bias voltage based on the optical signal modulated on the basis of the first electric signal.
