FIELD: measuring technology.
SUBSTANCE: invention relates to measuring technology using optical fiber, namely to fiber-optic security detectors, as well as to products, methods and means related to fiber-optic security detectors and their aspects. A dynamic fiber-optic sensor is claimed, which is a housing made with the possibility of fixing to a controlled structure, made with the possibility of non-rigid placement in it of a sensor element formed by a coil of optical fibers and a splitter, the outputs of which are closed to each other by the said coil and form a closed loop forming a reflection signal. Moreover, the splitter is designed to be connected to the transport part of the security fiber-optic detector, and the coil is placed loosely in the housing so that the vibrations of the sensor housing are transmitted to all the fibers of the coil.
EFFECT: elimination of the need to use electrical energy for the operation of a dynamic fiber-optic sensor, and the realization of its purpose by it.
