Light adjusting-type infrared radiation calibration method

The invention relates to the field of optical infrared radiation calibration, and provides a light adjusting-type infrared radiation calibration method. Through adjusting radiation flux incident to a calibrated device by blackbody radiation, irradiance radiated to the image surface of a calibrated system is changed, blackbodies with two temperatures are used at the same time, or the same blackbody changes temperature for one time, radiation flux incident to the calibrated system is calculated, and an infrared radiation response curve of the calibrated device is drawn. The common mode in which the temperature of the blackbody is adjusted to calibrate the device response curve is changed, the calibration speed is fast, influences such as background, radiation of the calibrated device itself and local output can be effectively removed, and the response curve of the calibrated curve can be drawn more accurately.
