Abstract

Support vector machine (SVM), is proposed to enhance the measurement accuracy of a temperature-tuning optical parametric oscillator (OPO) gas sensing system. The experimental results demonstrate that the minimum detecting concentration after the use of SVM decreases by more than 8 times..

Keywords
