静态偏振风成像干涉仪光传输特性和光通量改善

The static polarization wind imaging interferometer takes advantage of polarized-light beam to obtain interferogram, and beam transmission characteristic in core polarization components is a key issue. The Jones matrix is convenient and concise for analyzing the optics polarization state, and easy to obtain the relationship of key optical components in the system performance. The Jones matrix is introduced to describe the static polarization interferometer system respectively in a given case and in a general case. The variations of optical flux and interference fringe visibility are investigated as functions of polarization direction and wave plate azimuth associated with the key components, and their optimal values are ascertained. The optical flux can be improved by widening field of view and increasing the transmittance of the pyramid prism. The simulation results of the interference intensities confirm the theoretical expectations.The study provides a theoretical basis and practical guidance for the design, development and engineer of the static polarization wind imaging interferometer.
