Abstract
A LIDAR apparatus for scanning a scene, comprising a transmitter stage, a receiver stage, a beam-steering engine configured to steer the light beam received from the transmitter stage in different directions to scan at least a portion of the scene, the beam-steering engine being responsive to steering commands to produce corresponding deflections of the light beam and an operation monitor for monitoring a beam-steering function of the beam-steering engine.
Claims19
A LIDAR apparatus for scanning a scene, comprising:
- a. a transmitter stage,
- b. a receiver stage,
- c. a beam-steering engine configured to steer the light beam received from the transmitter stage in different directions to scan at least a portion of the scene, the beam-steering engine being responsive to steering commands to produce corresponding deflections of the light beam,
- d. an operation monitor for sensing a fault in a beam-steering function of the beam-steering engine.
A method for scanning a scene, comprising:
- a. providing a LIDAR apparatus having:
- i. a transmitter stage,
- ii. a receiver stage,
- iii. a beam-steering engine configured to steer the light beam received from the transmitter stage in different directions to scan at least a portion of the scene, the beam-steering engine being responsive to steering commands to produce corresponding deflections of the light beam,
- b. the method includes:
- i. receiving a sensor signal conveying an operational parameter of the beam-steering engine,
- ii. detecting at least in part from the sensor signal a fault in the beam-steering function of the beam-steering engine.
A method for scanning a scene, comprising:
- a. providing a LIDAR apparatus having:
- i. a transmitter stage,
- ii. a receiver stage,
- iii. a beam-steering engine configured to steer the light beam received from the transmitter stage in different directions to scan at least a portion of the scene, the beam-steering engine being responsive to steering commands to produce corresponding deflections of the light beam,
- b. the method includes:
- i. receiving data at an input of a data processor, wherein the data describes the scene, and it is derived at least in part from the LIDAR apparatus,
- ii. processing the data to detect a fault in the beam-steering function of the beam-steering engine.
