title: Method for measuring the cone angle and the shape of the axicon simultaneously using computer-generated holograms.
abstract: 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.
