Assignee: AMS SENSORS GERMANY GMBH
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 16:
17. A sensor system comprising:
an emitter operable to generate a first light wave;
a detector operable to detect a second light wave in response to the first light wave being reflected from a target object;
at least one temperature sensor operable to determine a temperature measurement that indicates a particular temperature at a respective section of the sensor system;
an analog-to-digital converter operable to obtain, from the one or more temperature sensors, 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; and
a temperature controller operable to:
compute temperature coefficients to regulate a temperature of the sensor system, each of the temperature coefficients being computed based on a difference between the first temperature and a reference temperature;
generate a control signal to regulate the temperature of the sensor system based on the computed temperature coefficients; and
regulate, 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.
