用位移测量仪测量角位移必须精确地测定双反射器组的几何基线。本文描述的装置能测定这样的基线。为了求得基线的数值,需要一块折射角为5°的已检定过的光楔。按已知的基线,并用已检定过的光楔(19′47″,1°18′48″,3°18′12″)在给定范围内确定角位移的测量误差。角位移测量原理是求出角隅反射器组相对于回转轴倾斜(?)角所产生的两光束的程差。图1
Measuring the angular displacement with a displacement gauge must accurately determine the geometrical baseline of the dual reflector group. The device described herein can determine such a baseline. To find the baseline value, a calibrated wedge with a 5 ° refraction angle is required. The known measurement of the angular displacement is carried out in a given range with the known baseline and using a certified optical wedge (19’47 “, 1 ° 18’48”, 3 ° 18’12 "). The angular displacement measurement principle is Find the difference between the two beams produced by tilting (?) The corner cube with respect to the axis of rotation.
