Title:
LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/115856
Kind Code:
A1
Abstract:
In the conventional laser radar device, when there is a mechanical scan angle dynamic range in a movable optical element for beam scanning, the problem arises that the view angle of the device is restricted due to limitation of the beam scanning range. This laser radar device is provided with: a light source for outputting laser light; a scanner for causing the laser light to scan; a first optical system on which the laser light caused to scan by the scanner is incident, and which emits the incident laser light so that the horizontal direction component of the incident laser light and the horizontal direction component of the emitted laser light are different; and a second optical system on which the laser light caused to scan by the scanner is incident, and which emits the incident laser light so that the incident range in the horizontal direction of the incident laser light and the incident range in the horizontal direction of the first optical system are the same, and the emission range of the incident laser light and the emission range of the first optical system are different.
