【Abstract】 This paper focuses on the principle of a wave front dividing interferometer for interference spectroscopy measurement,and proposes a theoretical model which adopts the scalar complex amplitude of the electric field to calculate the interferometer′s intensity distribution,the experimental results are like the raster.The relationships of wavelength,cycle constant,cycle count and the angle of refraction are discussed.The detecting of interference pattern is also concerned.The result of theoretical calculation is proved by the corresponding experimental result.In addition,the paper compares and analyzes the scanning methods of optical path difference (OPD).更多还原
