Claim 0:
1. A method performed using a sensor system, the method comprising:
generating, by an emitter of the sensor system, a first light wave;
detecting, by a detector of the sensor system, a second light wave in response to the first light wave being reflected from a target object;
obtaining, by a first converter and from one or more temperature sensors of the sensor system, a first temperature of the sensor system at least when the first light wave is generated by the emitter or when the second light wave is detected by the detector;
computing, by a temperature controller, temperature coefficients to regulate a temperature of the sensor system, where each of the temperature coefficients is computed based on a difference between the first temperature and a reference temperature;
generating, by the temperature controller, a control signal to regulate the temperature of the sensor system based on the computed temperature coefficients; and
regulating, by the temperature controller, the temperature of the sensor system by controlling an off-time of a driver circuit that causes the emitter to generate the first light wave,
wherein increasing the off-time of the driver circuit cools the detector and the emitter.
