Temperature-Corrected Oxygen Detection Based on Multi-Mode Diode Laser Correlation Spectroscopy
Figure 5
(Color online) concentration measurement evaluated by scheme . (a) Concentrations by using atmospheric oxygen as the sample gas at 9 different temperatures between 300 and 473 K; (b) normalized measurement results shown in (a) with the linear fit giving the effective temperature-correction coefficient expression; (c) evaluated concentrations before and after temperature correction by using a standard gas mixture containing 5.1% oxygen as the sample gas.
