FIELD: measurement equipment.
SUBSTANCE: invention relates to the field of interferometry. The system with interferometers comprises a fibre-optic sensor, which may have a part of a Michelson sensor and a part of a Mach-Zehnder sensor. The first splitter-coupler may be configured to split light between the first fibre-optic part and the second optic-fibre part. The first coupling device of phase polarisation may be configured to couple the polarisation phase of falling light, corresponding to the first optic-fibre part, and the second device of polarisation phase coupling may be configured for coupling of falling light polarisation phase, corresponding to the second optic-fibre part. Each, first and second phase polarisation coupling devices may be configured to reflect light into the detector and via appropriate first and second optic fibre parts. The coupler may be configured to combine light in the first optic fibre part with light in the second optic fibre part, and the third optic fibre part may be configured to receive light from the coupler and for excitation of the second detector.
EFFECT: simplified design of a system for position detection or noise magnitude.
