Paper Abstract

In the usual surface forces apparatus arrangement, the determination of the distances between interacting surfaces, as well as their mutual forces, is based on the analysis of interference fringes originated between the surfaces. To enhances the contrast and sharpness of the fringes, a thin metallic coating is applied to the mica plates that form the interaction chamber. In this paper we try to improve the performance of the basic system just described by optimizing the metallic coating and also by computer processing the images of the visible fringes.
