本文介绍捷克计量研究所在多面棱体检定方法方面所取得的一些经验。多面棱体的检定原理,是将中心角同固定角作比较。固定角是由两自准直仪的瞄准轴线形成的。此外,还考虑多面棱体上相邻角的角度和等于360°。一些作者根据多面棱体的这一性质,作出了
This article presents some of the lessons learned by the Czech Institute of Metrology in the method of multi-faceted prism testing. The principle of multi-faceted prisms is to compare the center angle with the fixed angle. The fixed angle is formed by the aiming axes of both autocollimators. In addition, the angles of adjacent corners on a polygon are also considered to be equal to 360 °. Some authors have made this property based on polyhedral prisms
