Abstract

The invention discloses a calibration device of an infrared radiometer and a calibration method of the infrared radiometer, belonging to the field of infrared measurement. The device comprises a standard infrared radiation source, an infrared optical collimation system and a plurality of standard detectors and computers; the infrared optical collimation system is formed by a plane mirror and an off-axis parabolic mirror. The infrared radiation emitted by the standard infrared radiation source is received by a calibrated infrared radiometer or a standard detector directly or after being collimated by the infrared optical collimation system, and the measuring voltage of the collimated infrared radiometer or the standard detector is obtained correspondingly; the standard infrared radiation source is shielded, so that the collimated infrared radiometer or the standard detector receives the background radiation directly or via the infrared optical collimation system and correspondingly obtains the background voltage of the collimated infrared radiometer or the standard detector, thereby calculating the radiance responsiveness curve of the infrared radiometer. The device and the method disclosed by the invention solve the responsiveness calibration problem of large view infrared radiometer, and the calibration precision is high.

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.

[0003] Foreign countries generally use the device described below to c...
