A fibre-optic sensor working according to the Fabry-Perot principle has an open capillary piece (5) into which at least one optic fibre (1) is inserted in such a way that its inserted end surface forms with an optic reflecting surface a gap with parallel faces perpendicular to the axis ...
In the following discourse, we discuss the new physical principle and show the key concept behind calculating the wave sensitivity in a data-driven manner using multiple observation points and the boundary integral representation. We use the boundary integral representation in order to extrapolate the ...

The sections (13, 14) of the carrier (10) supporting the respective optical fibres (11, 12) have differing elasticity. A 2 by 2 coupler (15) connects the fibre input ends to a laser diode (16). The output ends of the fibres are combined by a 3 by 3 coupler (17) with all three...
