Since more than one decade, a new generation of microscopes was developed. It is about near field microscopes. Among these devices, we are interested in the PSTM (Photon Scanning Tunnelling Microscopy). Images obtained by this instrument do not reflect, with a better resolution, the topography of the studied samples. In order to improve the performance of this apparatus, several models have been developed. In our case, we propose to retake, by using a differential method, the study of a rough surface. The surface is modelled as two pavements of different sizes and refractive indices. Theoretically, the obtained results agree well with results obtained for a surface having submicronic asperities and subsurface structures found in literature.
