Dumbbell slider type optical fiber accelerometer and method for using the dumbbell slider type optical fiber accelerometer

Abstract

The invention provides a dumbbell slider type optical fiber accelerometer and a method for using the dumbbell slider type optical fiber accelerometer. Three chambers are sequentially provided in a casing in the longitudinal direction, two ends of a middle chamber are respectively provided with through holes communicated with the chambers at both ends, a cross bar main body in the middle of a dumbbell type slider is disposed in the middle chamber, the middle part of the cross bar main body is sleeved and fixed with an annular stopper, the cross bar main body at both ends of the annular stopperis respectively provided with springs, two ends of the cross bar main body respectively extend into the chambers at both ends through the through holes, a reflector is fixed on the outer side of a convex portion at one end of the cross bar main body, an optical fiber hole is provided at the position directly facing the reflector on the inner wall of the chamber where the convex portion is located,an optical fiber bundle extends from the exterior of the casing into the optical fiber hole, and the optical fiber bundle includes incident optical fibers and receiving optical fibers. The dumbbell slider type optical fiber accelerometer and the method for using the dumbbell slider type optical fiber accelerometer are used to solve the problem that the existing accelerometer is not applicable inmany occasions, is not strong in practicability, and cannot meet the actual acceleration measurement requirements, belonging to the technical field of optical fiber sensing.

Description

technical field [0001] The invention relates to a dumbbell slider type optical fiber acceleration sensor and a using method thereof, belonging to the technical field of optical fiber sensing. Background technique [0002] In modern industrial production, especially in the automated production process, various sensors are often used to monitor and control various parameters in the production process, so that the equipment can work in a normal or optimal state, and the product can achieve the best quality. Sensors have already penetrated into a wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relic protection. The present invention is one of many types of sensors—acceleration sensors. With the development of sensor technology, a variety of acceleration sensors have appeared, usually composed of mass blocks, dampers, elastic components...
