On a statistical analysis model of mid-IR gas sensing systems

Abstract

A mid-IR laser-based gas sensing system based on Laser-based spectroscopy (LAS) is an important application in numerous fields. We used detection theory to develop a generic statistical analysis model for mid-IR gas sensing systems to compute the different performance probabilities. A signal strength measure, ΔSNR , is defined to address the detection problem for the gas sensing system and to perform detection improvement analysis.
