Abstract

According to teaching and experimental requirements of Optoelectronic information science and Engineering，in order to consolidate theoretical knowledge and improve the students practical ability, the Fourier transform spectrometer ( FTS) experiment, its design, application and improvement are discussed in this paper. The measurement principle and instrument structure of Fourier transform spectrometer are introduced, and the spectrums of several common Laser devices are measured. Based on the analysis of spectrum and test，several possible improvement methods are proposed. It also helps students to understand the application of Fourier transform in physics.
