The relationship between the comprehensive deviation and dihedral angle error of the hollow corner cube reflector measured by interferometry is derived. The characteristics and interpretation rules of the interference pattern of the hollow corner cube reflector are summarized. A laser Twyman-Green interferometer is built to measure and analyze the angle error of a hollow corner cube reflector. Experimental results show that the accurate measurement of the angle error less than 1″ of the reflector can be realized by the theoretical method and laser Twyman-Green interferometer.
