Improving the Accuracy of Methane Sensor with Dual Measurement Modes Based on Off-Axis Integrated Cavity Output Spectroscopy Using White Noise Perturbation
A methane (CH<sub>4</sub>) sensor based on off-axis integrated cavity output spectroscopy (OA-ICOS) was developed, equipped with two measurement schemes: direct absorption spectroscopy (DAS) and wavelength modulation spectroscopy (WMS). The sensor used an optical resonant cavity composed...
