Infrared absorption spectroscopy (IAS) is currently a powerful tool for gas sensing. Gas sensors based on IAS show advantages of high sensitivity, good selectivity and in-situ measurement. Typical infrared include discrete optics, hollow-core fiber on-chip sensors, suitable different application environments. Discrete have relatively large volume heavy weight, but due to light-gas interaction length (tens meters or even kilometers), their sensitivity obviously higher than sensors. Mature...
