The influence of light intensity fluctuations can be eliminated by using scanned-wavelength direct absorption spectroscopy. 扫描波长直接吸收光谱学对光强度波动的影响可以消除。
In the present paper, a review and analysis of the theory of direct absorption spectroscopy and modulation spectroscopy using tunable diode ( laser ) were provided, and a remote sensing system of CH_4 was designed. 文章对可调谐二极管激光的直接吸收和波长调制光谱进行了理论分析,设计了一套用于研究甲烷吸收特性的测量系统。
