theoretic analyse and experiment about the right-angle prism axis s comparatively variety are mainly introduced.

Optical characteristics of right-angle roof prism and corner-cube prism;

The automatic test of Corner Cube Reflector (CCR), Roof Prism and Right-angle Prism is achieved by calculating the wavefront got from the digital phase-shifting interferometer.

Analyzing characteristic of the cube-corner retroreflector applied to laser straightness measurement;

By vector analysis the rectangular angle error influence on characteristics of the beam of cube-corner retroreflector;

Then,the effect on the first-harmonic nonlinearity by the polarization properties of reflected light of the cube-corner retroreflector and axial rotation in the motion direction of the measurement cube-corner retroreflector is derived.
