Paper Abstract

In this paper, one approach of angle measurement of optical wedge used dual-frequency laser interferometer is referred. The asymmetry of the optical corner cubes in reflector housing is analyzed which has a notable effect on the uncertainty of the measurement result. The asymmetry is constituted by two components: ▵h, the height difference between optical corner cubes, and ▵α, the non-parallelism between two front surfaces of optical corner cubes. At last the influence of this error is obtained, and a precision compensation model for angle measurement is established. Keywords: dual-frequency laser interference, sinusoidal measurement angle, optical corner cube, asymmetry
