摘　　要：简述了自行设计的新型静态偏振风成像干涉仪的原理和四面角锥棱镜的分光机理;应用光线追迹法,推导出了主截面内任意光线在棱镜中的传播方向及出射点坐标,建立了平行光束经角锥棱镜后的偏向角和透过率的理论表达式;采用计算机模拟给出了偏向角和透过率随入射角的变化关系曲线;根据静态偏振风成像干涉仪的具体参数确定了四面角锥棱镜的侧面和底面夹角以及底边长度.该研究为静态偏振风成像干涉仪的研制提供了理论依据.The principles of the new static polarization wind imaging interferometer and the light beam splitting of the four-sided pyramid prism were briefly introduced. Both the li ghtray’s transmitting direction and the transmitted point coordinates in the section of the prism were deduced by the ray tracing method. When the parallel ray had passed through the four-sided pyramid prism, the relation between the in cidence angle and the deviation angle was calculated, the relation between the inc idence angle and the transmissivity was also calculated. All the above relations were simulated by the computer. According to the parameters of the static polarization wind imaging interferometer, both the angle between the side and the base and the length of the base were determined. This research was very important to the design and manufacture of the static polarization wind imaging interfe rometer.
