[0002] The method of using optical remote sensing to monitor various pollutant gases in the environment has been increasingly widely used. Most optical remote sensing equipment needs to be accurately calibrated with standard gases before normal operation, especially when measuring with non-dispersive infrared solutions and the measured gas has nonlinear absorption in the high concentration range. Daily calibration of the equipment is an essential step; especially for nonlinear calibration, there is no fixed and unified formula for remote sensing equipment. Most of them are calibrated based on the empirical values ​​measured by the equipment, or based on the concentration of a gas.
