An axicon is an optical element with rotational symmetry and cone shape, which is nowadays widely used in many fields of engineering, like laser beam shaping, imaging systems, optical testing, laser machining, etc. In this paper, we propose a new method to measure the cone angle and the shape of the axicon simultaneously by using a computer-generated hologram. This test is performed in a null-test configuration. (C) 2015 Optical Society of America
