Compact Open-Path Sensor for Fast Measurements of CO<sub>2</sub> and H<sub>2</sub>O using Scanned-Wavelength Modulation Spectroscopy with <i>1f</i>-Phase Method

Compact Open-Path Sensor for Fast Measurements of CO<sub>2</sub> and H<sub>2</sub>O using Scanned-Wavelength Modulation Spectroscopy with <i>1f</i>-Phase Method

We report here the development of a compact, open-path CO<sub>2</sub> and H<sub>2</sub>O sensor based on the newly introduced scanned-wavelength modulation spectroscopy with the first harmonic phase angle (scanned-WMS-θ<i>1f</i>) method for high-sensitivity, high...
