光検出装置
Document Type and Number:
Japanese Patent JP7367655
Kind Code:
B2
Abstract:
A LiDAR device is an optical device, including a light-emitting unit, a scanning unit, a light-receiving unit, and an optical unit. The light-emitting unit includes a plurality of laser oscillation elements respectively emitting a beam in an arrangement along a light source array direction at intervals from each other. The scanning unit projects the beam to a measurement area by scanning of the beam that is emitted from the light-emitting unit. The light-receiving unit receives a reflected beam from the measurement area. The optical unit is positioned on an optical path of the beam directed from the light-emitting unit to the scanning unit. The optical unit includes a collimator lens having a positive power in a transmission direction of the beam, and a beam shaping lens positioned behind the collimator lens and having a positive power in the transmission direction on a sub-scanning plane.
