Paper Abstract

The recent research progress of the Shandong University research group on the performance improvement of tunable diode laser absorption spectroscopy (TDLAS) fiber gas sensor is presented in this paper. The artificial absorption peak technology and the balanced ratiometric detector (BRD) technology are developed to improve the resolution of the TDLAS fiber optical gas sensor. The method for eliminating background absorption interference, the reliability study and the elimination technology of the residual amplitude modulation (RAM) are studied to improve the accuracy of the TDLAS fiber optical gas sensor. We will continue to conduct the next investigation and research in this field on the basis of existing theories and technologies.
