Principle and Performance Analysis of the Levenberg–Marquardt Algorithm in WMS Spectral Line Fitting
Calibration-free wavelength modulation spectroscopy (WMS) is an efficient technique for trace gas monitoring. It is widely used due to its resistance to light intensity fluctuations, strong suppression of low-frequency noise, fast response time, and excellent environmental adaptability. The calibrat...
