FIELD: physics.
SUBSTANCE: invention is related to fibre-optical measuring equipment, in particular, to fibre-optical measuring systems of pressure, temperature, deformation, displacement gaging. System contains wideband source of emission, interferometer Fabry-Perot, focusing system, registering interferometer and photo-registering facility, optical Y-shaped coupler, analog-digital transducer, microprocessor device. Wideband source of emission is made with fibre-optic output, which is connected with optical Y-shaped coupler. Coupler is connected with interferometer Fabry-Perot and with focusing system. Registering interferometer is made in the form of polarisation interferometer. System may represent multichannel versions of measuring system with spatial and time division of channels.
EFFECT: reduction of assembly labour intensity, increase of signal/noise ratio.
