Vehicle lidar

The transceiver module of the liDAR is fixed, and the double prism is driven by a motor to rotate at high speed. The first deflection of the laser occurs after passing the first wedge prism, and the second deflection occurs after passing the second wedge prism. The scanning pattern of the laser can be controlled as long as the relative speed of the two prisms is controlled. Refracted light at different angles is generated to achieve coverage of higher wiring bundles in the FOV range.

Rotating mirror

The laser direction of LiDAR laser is a polygon mirror that can rotate around the center, and the laser scanning is realized by rotating the mirror of the motor, which has the advantages of fixed device, small volume, low cost and easy to pass the vehicle regulation.
