Distortion correction method of line shape based on harmonic detection
When wavelength modulation spectroscopy is used for gas detection in open space, the second harmonic signal is modified due to the interference of optical noise, uncontrollable environmental noise, etc., resulting in the distortion of the line shape, which affects the measurement accuracy. In this s...
