Power Modulation for a Rotary Light Detection and Ranging (LIDAR) Device
An example method involves rotating a sensor that emits light pulses and detects reflections of the emitted light pulses based on a pointing direction of the sensor. The method also involves identifying a range of pointing directions of the sensor that are associated with a target region of an envir...

description | An example method involves rotating a sensor that emits light pulses and detects reflections of the emitted light pulses based on a pointing direction of the sensor. The method also involves identifying a range of pointing directions of the sensor that are associated with a target region of an environment. The method also involves determining whether a current pointing direction of the sensor is within the identified range. The method also involves modulating the emitted light pulses according to a first modulation scheme in response to a determination that the current pointing direction is within the identified range. The method also involves modulating the emitted light pulses according to a second modulation scheme in response to a determination that the current pointing direction is outside the identified range. The second modulation scheme is different than the first modulation scheme. |
