title: [An interferometer design for Fourier transform infrared spectrometer].
abstract: A novel interferometer system based on the combinations of cube-corner reflectors and fixed plane mirrors was designed to improve the quality of spectra. It consists of a pair of cube corner reflectors, two fixed perpendicular plane mirrors and one beam splitter. By analyzing the modulation depth and phase error, the tilt and shearing of the cube corner reflectors, the deviation angle of cube corner reflector, the tilt of fixed plane mirrors and the deviation angle of two fixed plane mirrors were analyzed. It was proved that the tilt and shearing of the cube corner reflectors, and the deviation angle of two fixed plane mirrors, have no effects on the modulation depth and phase error of this new interferometer system, and the effect from the vibration, temperature fluctuations and other external environmental factors also can be effectively reduced, which can significantly improve the spectral resolution and quality. Through some experiments, it was found that the instrument has a simple structure, good sealing, high resolution, strong stability and other advantages
