This paper deals with some recent applications of image analysis techniques to film thickness measurement. It aims at listing the main contributions and the identified applications. We will first recall the classical technique of optical interferometry. Then, the main different approaches for the numerical treatment of interferograms are presented. It is shown that these techniques fulfil the requirements mentioned above, opening new possibilities for researchers. In the second part of the paper, applications to various problems are presented. Film thickness measurements performed on a rough static contact, then on a smooth dynamic one, under EHD and thin film regimes, are reported. Finally, from film thickness mapping, we show that it is also possible to evaluate other parameters, such as the pressure that can be determined everywhere in the contact with a very good spatial resolution.
