Abstract

A planar-beam, light detection and ranging (PLADAR) system can include a laser to output a laser beam and a collimator configured to collimate the laser beam axially to emit a planar beam from the laser. The PLADAR system can further include a detector to detect reflected light based on the planar beam being reflected from external surfaces of target objects.

Claims (32)

1. A planar-beam, light detection and ranging (PLADAR) system, the PLADAR system comprising:

a laser to output a laser beam;

a collimator configured to collimate the laser beam on an axis to emit a planar beam laser along a beam plane; and

a detector array to detect reflected light based on the planar beam being reflected from external surfaces of target objects, the detector array comprising a plurality of photodetectors arranged on a circuit board such that each of the photodetectors is aligned with the beam plane.

2. The PLADAR system of claim 1 , wherein the laser comprises a fiber laser that outputs the laser beam.

3. The PLADAR system of claim 1 , wherein the collimator comprises a set of mirrors that produce the planar beam from the laser beam.

4. The PLADAR system of claim 1 , wherein the collimator comprises a set of lenses that produce the planar beam from the laser beam.

5. The PLADAR system of claim 1 , wherein the plurality of photodetectors include at least one row of photodetectors, and wherein the circuit board includes a number of adjustment components to calibrate each photodetector included in the at least one row of photodetectors.

6. The PLADAR system of claim 5 , further comprising:

an adjustment controller that dynamically adjusts the adjustment components to configure the at least one row of photodetectors in response to a command signal.

7. The PLADAR system of claim 5 , wherein the PLADAR system is included on an autonomous vehicle comprising a control system that processes sensor data from the PLADAR system to dynamically identify features as the autonomous vehicles accelerates and maneuvers.

8. The PLADAR system of claim 7 , further comprising:

an analog to digital converter (ADC) chain coupled to the at least one row of photodetectors;

wherein the control system of the autonomous vehicle samples data from each ADC of the ADC chain simultaneously.

9. An autonomous vehicle comprising:

acceleration; braking, and steering systems;

a control system to autonomously operate the acceleration, braking, and steering systems; and

a planar-beam, light detection and ranging (PLADAR) system, the PLADAR system comprising:

a laser to output a laser beam;

a collimator configured to collimate the laser beam on an axis to emit a planar beam along a beam plane; and

a detector array to detect reflected light based on the planar beam being reflected from external surfaces of target objects, the detector array comprising a plurality of photodetectors arranged on a circuit board such that each of the photodetectors is aligned with the beam plane.

10. The autonomous vehicle of claim 9 , wherein the laser comprises a fiber laser that outputs the laser beam.

11. The autonomous vehicle of claim 9 , wherein the collimator comprises a set of mirrors that produce the planar beam from the laser beam.

12. The autonomous vehicle of claim 9 , wherein the collimator comprises a set of lenses that produce the planar beam from the laser beam.

13. The autonomous vehicle of claim 9 , wherein the plurality of photodetectors include at least one row of photodetectors, and wherein the circuit hoard includes a number of adjustment components to calibrate each photodetector included in the at least one row of photodetectors.

14. The autonomous vehicle of claim 13 , the PLADAR system further comprising:

an adjustment controller that dynamically adjusts the adjustment components to configure the at least one row of photodetectors in response to a command signal.

15. The autonomous vehicle of claim 13 , further comprising:

a control system that processes sensor data from the PLADAR system to dynamically identify features as the autonomous vehicle accelerates and maneuvers.

16. The autonomous vehicle of claim 15 , the PLADAR system further comprising:

an analog to digital converter (ADC) chain coupled to the at least one row of photodetectors;

wherein the control system of the C samples data from each ADC of the ADC chain simultaneously.
