Abstract:
1. A calibration system comprising: an infrared thermometer having an emissivity setting; a target emitting infrared radiation toward the infrared thermometer; a heating element in thermal contact with the target; a temperature sensor in thermal contact with the target; and a controller coupled to the temperature sensor and heating element, the controller configured to receive an input temperature, the controller programmed to map the input temperature to a set temperature and to cause the heating element to heat the target to proximate the set temperature, the set temperature corresponding to an apparent temperature of the target equal to the input temperature, the apparent temperature being substantially equal to a graybody temperature of a graybody having an emissivity substantially equal to the emissivity setting of the infrared thermometer and having a radiance substantially equal to the target when heated to the set temperature.
