M-Z干涉仪干涉条纹畸变对比度M-Z Interferometer Interference Fringes Distortion Contrast



By observation experimental effect, the distortion of the shape of M-Z the interference fringes is found. Light intensity distribution of the interference fringes is analyzed using calculation software. And the reason that generates the distortion is solved by coherent theory, and the main factors that may affect M-Z interferometer fringe shape and contrast is analyzed from aspect emitting mechanism of the light source, the experimental optical path and the light utilization, etc. The improvement measures of corresponding have been presented. And the results that improved interference fringes are closer to the straight fringes than the interference fringes before improvement are obtained. The paper provides a useful reference for further improving fringe contrast and research areas of relate interference fringes.
