Abstract
Description
technical field
[0001] The invention belongs to the field of infrared optical measurement, and relates to a device for calibrating the irradiance responsivity of an infrared radiometer and a calibrating method thereof. Background technique
[0002] The calibration of the infrared radiometer is mainly for the calibration of the irradiance responsivity of the infrared radiometer. The infrared standard radiation source with known radiation value is used to calibrate the infrared radiometer, and the output value (such as voltage value) of the infrared radiometer and the output value of the infrared radiometer are obtained. The relationship between the input radiation, the process is the calibration of the infrared radiometer. When other technical conditions are equal, the more accurate the known radiation value received by the infrared radiometer, the more accurate the resulting calibration result will be.
