Title:
LIDAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/121452
Kind Code:
A1
Abstract:
This LiDAR device comprises: an optical transmitter that is configured from a first optical phased array and transmits, into a space, diffracted light produced from light output from a plurality of first antenna elements composing the first optical phased array; and an optical receiver that is configured from a second optical phased array and uses a plurality of second antenna elements composing the second optical phased array to receive light arriving from the space. The optical receiver has a plurality of local maximum sensitivity directions each of which is a direction of the arrival of the light from the space in which the light reception sensitivity is at a local maximum. A first angle formed between adjacent directions of diffracted light transmitted into the space by the optical transmitter is different from a second angle formed between adjacent local maximum sensitivity directions of the optical receiver.
