A device for ellipsometric two-dimensional display of a sample placed in an incident medium, observed between an analyser and a polarizer intersected by convergent light reflection, wherein the ellipsometric parameters of the assembly formed by the sample and a substrate whereon it is placed, are used. The substrate comprises a support and a stack of base layers and its ellipsometric properties are known. The ellipsometric properties of the substrate are such that variations of the sample ellipsometric parameters are displayed with contrast higher that the contrast produced in the absence of the substrate. The invention also concerns a display method and an ellipsometric measurement method with spatial resolution. |
