In the transient temperature measurement of combustion field,the traditional intrusive measurement method has some problems,such as slow response speed and large accuracy deviation.However,there has been no suitable hardware system for absorption spectroscopy.Therefore,aiming at such problems,this paper builds a hardware system for temperature measurement of direct absorption method based on tunable semiconductor absorption spectroscopy (TDLAS) to detect the temperature of combustion field.The experiment platform is built to select the spectral line of center frequency(6 807.835 cm-1and 7 182.949 6 cm-1).With H2O as the target molecule,through the MATLAB temperature measurement analysis,the hardware system is verified to be effective and feasible,and can achieve the accurate measurement of the transient temperature of the combustion field within 10%.
