A system includes a sensor housing and a sensor processor external to the sensor housing. The sensor housing includes an infrared detection module and a thermoelectric module proximate to the infrared detection module. The infrared detection module is configured to detect infrared radiation of a scene and generate a measurement associated with the infrared radiation. The thermoelectric module is configured to provide thermal control to the infrared detection module based on a modulated power signal. An accuracy of the measurement is based on the thermal control provided to the infrared detection module. The sensor processor is configured to transmit a power signal to the infrared detection module and transmit a direct current power signal to the thermoelectric module. The direct current power signal is based on the modulated power signal.

Infrared sensors

A system for performing grazing angle measurements is disclosed herein. The system includes a laser configured to emit a beam of light and a series of reflective elements configured to direct the beam of light and a hollow sphere is rotatable about a sphere axis with the sphere axis extending through a central region of the hollow sphere. The hollow sphere defines an elongated slot for accepting the beam of light when the hollow sphere is in one of a plurality of predetermined rotational positions about the sphere axis. A mounting arm extends into a central region of the hollow sphere and includes a sample mount configured to receive a sample. The system further includes a spectral hemispherical reflectance detector having a field of view extending into the hollow sphere and a baffle horizontally interposed relative to the sphere axis between the spectral hemispherical reflectance detector and the elongated slot.
