Abstract

Abstract

The surface temperature measurement of temperature target based on a medium wave infrared detector was researched theoretically and experimentally in this paper. The constitution and measurement principle of the system were introduced and a temperature measurement model for the infrared detector was established. The gray drift characteristics of the infrared detector in a calibration were analyzed, and the drift disciplinarians were summarized by four kinds of different experiments. Meanwhile, the drift compensation method was proposed based on the drift disciplinarians. Finally, a temperature measurement experiment was carried out, and the results show that the measurement error before and after drift compensations are 1.965 ℃ and 0.335 ℃, respectively, which indicates that the measurement precision has been improved in a great degree after the compensation.
