FIELD: fiber-optic measuring devices and sensors. SUBSTANCE: the device uses a phase modulator, photodetector, signal generating and processing unit connected to the photodetector output and modulator, uses is made of two fiber sections; the first section is located before the fiber interferometer and intended to transmit optical radiation to the input of the fiber interferometer, the second section is positioned between the fiber interferometer and photodetector and intended to transmit optical radiation from the output of the fiber interferometer to the photodetector input, and the phase modulator is installed on the first fiber section. EFFECT: expanded field of application due to removal of the interferometer from the source of optical radiation, photodetector, and signal generating and processing unit. |
