Infrared sensors

A method comprising:

• detecting, by an infrared detection module, infrared radiation of a scene;
• generating, by the infrared detection module, a measurement associated with the infrared radiation of the scene;
• and
• providing, by a thermoelectric module proximate to the infrared detection module, thermal control to the infrared detection module based on a modulated power signal and a monitored temperature of the infrared detection module,
• wherein the thermoelectric module is configured to provide a cooling effect to the infrared detection module based on a first polarity of the modulated power signal,
• wherein the thermoelectric module is configured to provide a heating effect to the infrared detection module based on a second polarity of the modulated power signal,
• wherein a magnitude at which the thermoelectric module cools or heats the infrared detection module is based on a direct current power signal,
• wherein the direct current power signal is based on the modulated power signal,
• wherein an accuracy of the measurement is based on the thermal control provided to the infrared detection module,
• wherein a sensor housing comprises the thermoelectric module and the infrared detection module, and
• wherein a sensor processor, external to the sensor housing, transmits a power signal to the infrared detection module and transmits the direct current power signal to the thermoelectric module.

A non-transitory computer-readable medium comprising instructions that, when executed by a sensor processor external to a sensor housing, cause the sensor processor to perform operations comprising:

• transmitting a power signal to an infrared detection module within the sensor housing, the power signal causing the infrared detection module to:
• detect infrared radiation of a scene;
• and
• generate a measurement associated with the infrared radiation of the scene;
• and
• transmitting a direct current power signal to a thermoelectric module within the sensor housing,
• wherein the direct current power signal causes the thermoelectric module to provide thermal control to the infrared detection module,
• wherein the thermoelectric module is configured to provide a cooling effect to the infrared detection module based on a first polarity of a modulated power signal,
• wherein the thermoelectric module is configured to provide a heating effect to the infrared detection module based on a second polarity of the modulated power signal,
• wherein a magnitude at which the thermoelectric module cools or heats the infrared detection module is based on a direct current power signal,
• wherein the direct current power signal is based on the modulated power signal,
• wherein an accuracy of the measurement is based on the thermal control provided to the infrared detection module, and
• wherein the thermoelectric module is proximate to the infrared detection module.
