In this paper, we employ correlation spectroscopy method to detect gases and gas mixtures which have multi-line absorption in near infrared. The theories of correlation spectroscopy are discussed and a new modulation measure is proposed, which inherits the excellence of the correlation spectroscopy and makes the modulation easy. Then we compare this method with the traditional correlation spectroscopy method.
