Paper Abstract

The method presented in the paper permits a global observation of the contours of any diffusing object, in real time, with both a varying sensitivity able to reach 10 μm or even less, and a possible choice of the orientation of the reference plane in the same measurement. It is related to multiplicative moire methods but does not need the use of a filtering grid, nor the preliminary registration of a phase or amplitude image, but involves only interference phenomena, due to a particular use of Sagnac interferometer. Because the interchangeability of analysed objects may be carried out without any delay, and contouring of larger objects by scanning is very easy, this method is well adapted to routine controls of the topology of any small diffusing surfaces, for example rake faces of cemented carbide tool inserts. Theoretical explanations, experimental results and also theoretical and practical performances and limitations of the method are presented in this paper, so that its field of application is well determined.
