多面棱体是很普遍使用的角度基准器,目前高精度测角仪多用多面棱体的全组合法进行检定。但多面棱体制造比较困难,用全组合法检定,使得检定过程和数据处理非常复杂,检定时间拖长。考虑到上述问题,认为有必要探索一种快速、精度高,易于实现半自动化的检定手段。所采用的方法是自准直干涉测角法。在泰曼干涉仪的测量臂用两块反射镜组成一个 Multi-faceted prism is a commonly used angle of reference, the current multi-angle high-precision goniometer multi-faceted prism combination of the test method. However, the manufacture of polyhedral prisms is more difficult, with the full portfolio of test, making the test process and data processing is very complicated, prolonged test time. In view of the above problems, it is considered necessary to explore a rapid, high precision, easy to implement semi-automatic test means. The method used is self-colliding interference goniometry. The measuring arm in the Teijin interferometer is made up of two reflectors
