Abstract
A calibration system for sensors is provided. The calibration system includes an array of blackbody elements. Each blackbody element includes a high emissivity surface. The high emissivity surface can be formed using carbon nanotubes. In addition, each blackbody element includes a heating element and a temperature sensor. The heating element is operated to bring the blackbody element to a set point temperature, as determined by the temperature sensor. As an example, the calibration system can be used in connection with sensors sensitive to infrared wavelengths that is carried by a satellite or other platform.
