Abstract:According to the requirement of spectrometer design, including high-speed, simplified structure, convenient fabrication and real-time measurement, a static Fourier transform spectrometer(SFTS) was introduced and its theory was derived and analyzed. In order to solve the correction problem of tilting interference fringe in the adjustment process of SFTS, mathematical derivation of the model of interference fring was systematically summarized. Meanwhile, the mathematical relationship between the rotation parameter of tilting mirror and the minimum clear aperture and that between the rotation parameter of tilting mirror and the rotation parameter of interference fringe were obtained by mathematical derivation. Besides, by using Matlab, the model of interference fringe was simulated, and the correction formula for monochromatic light was proofed. The simulation results show that the precision of tilting angle correction is 1.4%, suggesting that it is a feasible and effective correction method.
