Abstract
The following describes a new procedure used for the classification of local defects on optical surfaces by use of the observer's eye contrast threshold. A new apparatus which works in transmission or reflection was constructed and tested. We will describe the principle and give the results of the experiments carried out with this work station. This study was financed by the Centre Technique des Industries Mecaniques and the Centre National de la Recherche Scientifique. Technical follow up was provided by the Groupement des industries francaises de l'optique.
