FIELD: electro-optical engineering. ^ SUBSTANCE: fiber-optic sensor system can be used in physical value fiber-optic converters providing interference reading out of measured signal. Fiber-optic sensor system has optical radiation laser detector, interferometer sensor, fiber-optic splitter, photodetector and electric signal amplifier. Interferometer sensor is equipped with sensitive membrane. Fiber-optic splitter is made of single-mode optical fibers. Connection between fiber-optic splitter and interferometer sensor is based upon the following calculation: l=0,125lambdan±0,075lambda, where l is distance from edge of optical fiber of second input of fiber-optic splitter to light-reflecting surface of sensor's membrane (mcm); lambda is optical radiation wavelength, mcm; n is odd number within [1001-3001] interval. ^ EFFECT: simplified design; compactness; widened sensitivity frequency range. ^ 4 cl, 1 tbl, 3 dwg |
