Abstract

Optical traditional interferometers are usually used to evaluate the form of spherical and plane surfaces; those systems could also assess the quality of aspheric surfaces which are quasi-spherical. But if a general aspheric surface is to be evaluated, this procedure requires the purchase of complicated and very expensive devices, such as aspheric interferometer, null-lenses, and computer generated hologram for each aspheric surface. This article presents a solid method allowing the measurement of a wide range of conical aspheric surfaces. This method is based on inserting plane-parallel plate (PPP) within the path of a laser beam coming out of a traditional Fizeau interferometer. This article also presents a mathematical justification that relates the conical surface parameters to the thickness of the inserted PPP. The article also presents the supporting computer simulations and some practical results of applying this method and its range of use.
