Humidity enhanced N2O photoacoustic sensor with a 4.53 μm quantum cascade laser and Kalman filter
A high-sensitivity N2O photoacoustic sensor using a 4.53 μm quantum cascade laser was developed. Sharply enhancement of photoacoustic signal of N2O with the increasing of humidity was investigated experimentally. Finally, 2.3 % water vapor was added to the analyzed sample to improve the vibrational-...
