The aim of the paper is to discuss the concept of a method for non-invasive, in situ characterization of a glass fibre diameter. The method involves the use of low-coherence radiation as a measurement tool. The essence of the method is to influence the spectral properties of the incident light in such a way to obtain the scattered field at a small angle easy to explain both, from the physical as well as mathematical point of view. Some numerical examples demonstrate the properties of the scattered field. To obtain the fibre diameter, direct and reverse mathematical analysis will be introduced with the aid of a solution to the Huygens-Fresnel integral. An empirical research will be aimed to demonstrate some achievements in the formation and analysis of the filed scattered on an optical fibre.
