Abstract
Traditional laser temperature measurement method has a slow warning speed because of its poor temperature measurement scheme. To solve this problem, a new tunable laser temperature measurement method is designed based on the spectral absorption process. According to the number of atoms, the gas molecular types are divided, and then the absorption line broadening is set based on the absorption process. On this basis, according to the relationship between the output light intensity and the incident light intensity, a tunable laser temperature measurement scheme is designed. In the experimental part, the measurement model of gas concentration and temperature field was constructed according to the absorption area ratio, and two temperature environments of −70 ℃ and 210 ℃ were set. According to the test results, the warning speed of this method is 3.39 min, 4.13 min and 7.43 min faster than the three groups of traditional methods at −70 ℃, and 2.91 min, 4.08 min and 7.31 min faster than the three groups of traditional methods at 210 ℃. Therefore, this method is more timely.
