Method of detecting the variation of the diameter of an optical fibre and method of making an optical fibre

A luminous source (2) comprises a helium-neon laser (20) and expander (21). The resulting beam (F) is directed transversely across an optical fibre (1) and some light is diffused within a narrow sector defined by angles of 90 and 100 degrees from the direction of the incident light. The diffused lig...
