ABSTRACT:
A device is provided forming a strictly ring interferometer having a ring formed by a monomode fiber, a source, separation and recombination means, and a monomode fiber segment forming mode filter. According to the invention, this monomode fiber segment is provided with a shutter generating directional losses intercepted by an optoelectronic detection member.
