Abstract

This paper describes the possibility to determine the statistical caracteristics of a reflecting diffusor (tooth or dental restorations samples with different qualities of polish) by means of holographic correlation. A modified Vander Lugt method is used to measure the local roughness and the lateral mean dimensions of diffusing elements of the surface. This non-destructive method allows surfaces to be tested without preparation, and the quality of polish and finish of tooth or dental restoration to be checked in their actual aspect. A comparison with S.E.M. method is also presented.
