摘要:Wavelength modulation spectroscopy combined with signal-reference beam method is used for trace gas detection. The developed technique combines the advantages of common-mode noise suppression and signal-to-noise ratio improvement. The performance of the resulting water vapor sensor is markedly improved because of scanning baseline suppression, effective suppression of the target gas content in the components and resistance to external factors such as temperature and humidity. Trace water vapor detection experiments verify that the measurement accuracy of the system can reach 1 ppmv for an optical path length of 10 cm.
