Hartmannometer versus Fizeau Interferometer: advantages and drawbacks

Abstract

In this paper we consider two approaches widely used in optical testing:Shack-Hartmann wavefront sensor and Fizeau interferometer technique.Fizeau interferometer that is widely used in optical testing canbe easily transformed to a device using Shack-Hartmann wavefrontsensor, the alternative technique to check optical components. Wecall this device Hartmannometer, and compare its features to thoseof Fizeau interferometer.
