A Compact NO<sub>2</sub> Gas Sensor with an Optimized Photoacoustic Cell and 450 nm-LD
In this paper, a compact ambient gas sensor with an optimized photoacoustic cell is reported. The relationship between the geometric dimensions (usually radius and length) of the photoacoustic cell (PAC) and the acoustic signal was studied through theoretical and finite element analysis. Then an opt...
