Tunable Diode Laser Absorption Spectroscopy Many of the first demonstrations of remote gas sensing used integrated-path absorption usually in conjunction with a laser source. Examples included helium–neon, argon-ion, and carbon dioxide lasers. Subsequently, some successful practical devices were also mad...
The absorption line profile is characterized by the temperature-dependent, spectrally integrated line strength S(T), and the normalized (area=1) shape function g(ν,ν0), which is centered at the wavelength ν0. (Source: #47 High-speed tunable diode laser absorption spectroscopy for sampling-...
最后一个单词差一个Y，全称是tunable diode laser absorption spectroscopy （TDLAS）.这是一种测量技术（TDLAS），使用可调谐二极管激光和激光吸收光谱学，测量气体混合物中某种成分的浓度，如甲烷，水蒸气等。该技术的优势在于测量的阈值下线可以很低（即需要测量的某种成分浓度很低），同时还可计算出气体...
