Paper Abstract

In the past, several groups presented images with the PSTM, different kinds of optical fibers being used as a probe. This paper presents a comparison of the intensity collected by single mode and multimode fibers in the near field of a sample lit in total internal reflection (TIR). The sample used is a grating covered with 65 nm of silver and is illuminated at different angles of incidence. We analyze the effect of the characteristics of the fiber on the collected intensity as a function of the distance between the end of the fiber and the surface of the sample. To illustrate this result a calibrated sample has been imaged with different kinds of fibers.
