Paper Abstract

In this paper we describe an interferometric process using a polychromatic light source and a spectroscopic detection system. This method is used for surface metrology or for bulk optical components characterisation (dispersion for example). As classical monochromatic interferometry, it consists in comparing a reference wave front with one issued from the component to be tested. However this measurement is assumed by determination of the spectral dispersion induced upon the various frequencies of the light source spectrum. The aim of this work is both dispersion measurements and characterisation of aspherical surfaces
