FIBRE-OPTIC DEVICE FOR DETECTING DISPLACEMENT Russian patent published in 2025 - IPC G01B11/00 

FIELD: measuring.

SUBSTANCE: invention relates to measurement equipment, namely to displacement sensors, and can be used to register displacement. Fibre-optic device for detecting displacement has a housing made from a movable part and a fixed part with the possibility of being connected to a radiation source and receiver. Between the movable and fixed parts there is an elastic element made in the form of one or more springs. Optical fibre is attached to the movable and fixed parts, wherein the movable element is made with possibility of displacement leading to deformations in the recording part of the optical fibre and changes in transmitted and reflected radiation. Recording part of the optical fibre is made in the form of one or more loops with the possibility of controlled macrobending to change radiation.

EFFECT: possibility of continuous registration of displacement of the controlled object, expanding the arsenal of technical means of registering displacement, simplifying the optical scheme of the device, avoiding the need to adjust the operating point before operating the device, as well as the possibility of transmitting measurement information to a remote terminal directly without additional processing.
