中文摘要：

从经典迈克尔逊干涉仪结构出发,主要分析了四种旋转型干涉仪的结构特点,以及干涉仪的光程差与旋转角度之间的关系。通过设定参数,使用干涉仪光程差表达式对这四种旋转型干涉仪的光程差作了模拟仿真。在干涉仪光程差表达式基础上,对这四种旋转型干涉仪的旋转速度与旋转角度之间关系也作了模拟仿真。通过对干涉仪光程差的模拟仿真和比较,能够直观地反映出干涉仪光程差与旋转角度之间的关系。在要求运动速度误差控制在3%以内情况下,讨论了四种旋转型干涉仪的旋转角度范围。通过对干涉仪的光程差分析和仿真,这对于研究干涉仪的结构和性能分析具有很好的借鉴意义。

英文摘要：

The four kinds of the structure characteristics of rotary type interferometer are mainly analyzed from the classical Michelson interferometer structure in the paper.The Optical path difference between the interferometer and the rotation angle is also analyzed.By setting parameters,the four kinds of rotary type optical path difference of the interferometer are simulated based on the optical path difference formula.The rotation velcocity of the four kinds of interferometers is also simulated.By simulation and contrast of the optical path difference,the relationship is intuitively reflect by figure between the optical path difference and the rotation angle.The scope of the rotation angle is discussed within 3% of the velocity errors.It is the very good reference significance to study the structure and properties of the interferometer by analyzing and simulating the optical path difference discussed in the paper.
