Abstract
Systems and methods herein provide for Laser Detection and Ranging (Lidar). In one embodiment, a Lidar system includes a laser operable to propagate continuous wave (CW) laser light and a scanner operable as a transmitter and a receiver for the CW laser light. The Lidar system also includes a detector for determining a range to a target based on displacement of the CW laser light received by the receiver. The displacement of the CW laser light is proportional to an angular velocity of the scanner.

A Laser Ranging and Detection (Lidar) system, comprising:
- a laser configured to propagate continuous wave (CW) laser light;
- a scanner configured as a transmitter and a receiver for the CW laser light;
- and
- a processor configured to calculate a range and an angle to a target, wherein the range and the angle are calculated using an angular displacement of the scanner arising from an angular velocity of the scanner.
A Laser Ranging and Detection (Lidar) method, comprising:
- transmitting continuous wave (CW) laser light via a scanner to a target;
- receiving at least a portion of the CW laser light scattered from the target via the scanner;
- and
- calculating a range and an angle to the target, wherein the range and the angle are calculated using an angular displacement of the scanner arising from an angular velocity of the scanner.
A non-transitory computer readable medium comprising instructions that, when executed by a processor of a Laser Ranging and Detection (Lidar) system, direct the processor to:
- receive at least a portion of transmitted continuous wave (CW) laser light scattered from a target and reflected from a scanner;
- and
- calculate a range and an angle to the target, wherein the range and the angle are calculated using an angular displacement of the scanner arising from an angular velocity of the scanner.
