Abstract
Embodiments discussed herein refer to a relatively compact and energy efficient LiDAR system that uses a multi-plane mirror in its scanning system.
Claims31
A light detection and ranging (LiDAR) system for use with a vehicle, comprising:
- a housing configured to be mounted to a windshield of the vehicle, the housing comprising:
- a transceiver module operative to transmit and receive light energy;
- a polygon structure that defines a lateral angle of the field of view of the LiDAR system;
- and
- a moveable mirror positioned to redirect light energy passing between the transceiver module and the polygon structure, the moveable mirror operative to control an exit angle of light being redirected by the polygon structure, wherein the exit angle corresponds to a particular angle within a vertical field of view of the LiDAR system.
2 more elements
A light detection and ranging (LiDAR) system, comprising:
- a transceiver module operative to transmit and receive light energy;
- a structure that defines a lateral angle of the field of view of the LiDAR system;
- and
- a multi-plane mirror positioned to redirect light energy passing between the transceiver module and the structure, the multi-plane mirror operative to control an exit angle of light being redirected by the structure, wherein the exit angle corresponds to a particular angle within a vertical field of view of the LiDAR system.
1 more element
A light detection and ranging (LiDAR) system, comprising:
- a transceiver module operative to transmit and receive light energy;
- a first mirror that defines a vertical angle of a field of view of the LiDAR system and oscillates in one of a direct drive mode and a resonant drive mode;
- and
- a second mirror that defines a horizontal angle of the field of view of the LiDAR system oscillates in one of a direct drive mode and a resonant drive mode, wherein the first mirror oscillates along a plane that is orthogonal to an oscillation plane of the second mirror.
