Abstract
A light detection and ranging system includes at least one laser that emits a laser beam. A beam steering device steers beams emitted by the laser at a desired angle. A curved mirror reflects the steered beams at any desired angle or direction. A method of providing a light detection and ranging system is also provided.
Claims23
A light detection and ranging system comprising:
- at least one laser that emits a laser beam;
- a beam steering device that steers beams emitted by the laser at a desired angle, the beam steering device being a liquid crystal grating;
- a curved mirror that reflects the steered beams at any desired angle or direction.
A light detection and ranging system, comprising:
- at least one laser configured to selectively emit a laser beam;
- a beam steering device for steering the emitted laser beam at a selected one of a plurality of available angles, the beam steering device being a liquid crystal grating;
- a curved mirror that reflects the steered laser beam at a predetermined trajectory responsive to the steered angle of the laser beam;
- a laser beam detector configured to detect a return signal corresponding to an interaction between an ambient object and the reflected laser beam;
- and
- a signal processor for receiving the return signal and responsively producing a lidar signal containing information about the ambient object.
A method of providing a light detection and ranging system, the method comprising:
- providing a system including a plurality of lasers, a beam steering device, and a curved mirror;
- emitting a plurality of laser beams from two or more of the plurality of lasers toward a single location on the beam steering device;
- with the beam steering device, steering each of the emitted laser beams emitted by the lasers at a desired angle toward the curved mirror;
- reflecting the steered laser beam from the curved mirror at a predetermined trajectory responsive to the steered angle of the laser beam;
- detecting a return signal corresponding to an interaction between an ambient object and the reflected laser beam;
- and
- receiving the return signal and responsively producing a lidar signal containing information about the ambient object.
A light detection and ranging system comprising:
- a plurality of lasers that each emits a laser beam toward a single location on a beam steering device;
- the beam steering device that steers the laser beams emitted by the lasers at desired angles toward a curved mirror;
- the curved mirror that reflects the steered beams at any desired angle or direction.
