Theoretical study of polarization atmosphere Michelsoninterferometer using multi-wavelength

The basic principle of measuring the upper atmosphere using the polarization atmosphere Michelson interferometer (PAMI) is briefly described. The relationships between the intensity and the visibility of the PAMI and the Delayed phase of the wave plate are presented. The visibility and the intensity of the PAMI are dependent on the wavelength of spectral line, showing that the 732nm line is inapplicable for measuring spectral line if the PAMI is designed specifically for the 630 nm line. The research provides a theoretical basis and practical guidance both for the theoretical study of polarization atmosphere Michelson interferometer and for the design and development of the new polarization atmosphere Michelson interferometer.
