Long-Term Stable Online Acetylene Detection by a CEAS System with Suppression of Cavity Length Drift
A trace acetylene (C<sub>2</sub>H<sub>2</sub>) detection system was demonstrated using the cavity-enhanced absorption spectroscopy (CEAS) technique and a near-infrared distributed feedback (NIR-DFB) laser. A Fabry⁻Perot (F⁻P) cavity with an effective optic...
