Abstract：To improve spectrum resolution of the traditional Fourier interferometer with the same size lens, was proposed based on orthogonal wedge Fourier interferometer system. The interferometer system gets the optical path difference by the prism of two mutually perpendicular, which can make the laser Interferences on the CCD Array. The detector use the area array CCD linear array CCD, and the system collected the interference fringes on the Two-dimensional plane. On the basis of the spectrum distribution of orthogonal inclination Moire interferometer by calculating optical path difference function, the system made the splicing of interference fringes on the area array CCD and Moire transform, finally got the spectrum resolution. The results from the MATLAB simulation software shows that the Maximum optical path difference of the orthogonal inclination Moire interferometer can be generated up to 234 μm, which is higher than the traditional Fourier interferometer about one order of magnitude, so the spectrum resolution also increased by nearly 10 times theoretical. Experimental calibration of the spectrometer with a selection of LAB SPAKR 750A-type spectrometer, measurements for the center wavelength of 635 nm semiconductor laser, the results show basically the same center wavelength position. However, the spectrum detected by orthogonal inclination Moire interferometer system near the center wavelength is better than the traditional interferometer system.
