Abstract
The utility model discloses an optical fiber assembly for an optical fiber sensor, which comprises a spiral optical fiber and a support component for fixing the optical fiber. The utility model is characterized in that the optical fiber is fixed on the support component by adopting the mode of a region (point). The utility model is designed and improved against the defect that the optical fiber is wound on an optical fiber assembly of an elastic support body in the existing optical fiber sensor, and because the elasticity of the elastic support body is easily influenced by environmental temperature and material aging, the stability of the optical fiber is influenced. Because the middle part of the spiral optical fiber is not provided with the elastic suyport body, the utility model can avoid that the hardness of the elastic support body is influenced because the elastic support body is easily influenced by the environmental temperature and the aging of self material, and the utility model also avoids that the stability of the optical fiber is influenced because the optical fiber is also influenced by the hardness change of the material of the support body.
Description
Technical field
The utility model belongs to optical fiber measurement instrument parts, is specifically related to a kind of optical fiber component that is used for Fibre Optical Sensor.
Background technology
At present, optical fiber measurement instrument, particularly optical fiber vialog are big owing to the dynamic range with bandwidth, amplitude, distortion is little, and characteristics such as sensitivity height are more and more used in engineering, equipment and scientific research.Fibre Optical Sensor is a critical piece of this instrument, and its principle of work is to utilize the microbending effect of optical fiber, and external force (vibration) is acted on optical fiber, make optical fiber generation deformation, and make and wherein transmit light and produce microbending loss, by detecting the variation of output light, thereby can determine the size of external force.In the existing Fibre Optical Sensor, optical fiber generally is to be wrapped on elasticity (as the rubber) supporter to form optical fiber component.This optical fiber component has an outstanding defect, and elastic support is subjected to the influence of temperature and self material aging easily.When temperature variation or material aging, the hardness of supporter also changes, and influences the little curved of optical fiber, causes the measurement data index to determine, directly influences measurement result.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes optical fiber component in the existing fiber sensor, and a kind of new optical fiber component is provided.This optical fiber component has stability preferably, is not subject to the influence that temperature variation is not subjected to propping material yet.
The technical scheme that realizes the present utility model purpose is: the optical fiber curl, optical fiber adopts and is fixed on the support component in position (point) mode.Scheme is on each circle on the optical fiber or all has a position (point) or more than one position (point) to be fixed on the support component on several circles at interval preferably.Support component is good with hard material, it can be different shape, as support, framework, tabular, strip, box-like etc., the mode that optical fiber is fixed on the support component also can be multiple mode, as optical fiber being passed support zone on the support component, sonet card being gone up, optical fiber is fixed on the support component with fixed part (as card, sheet etc.) in the stationary installation on the support component (as groove, collude, sheet etc.).
Design of the present utility model is to be wrapped in optical fiber component on the elastic support at optical fiber in the existing fiber sensor, because elastic support is subject to environment temperature and material aging influences elasticity, thereby the improvement carried out of this defective of stability that influences optical fiber, its design philosophy is to remove the middle elastic support of optical fiber, makes optical fiber not be subjected to the influence of supporter when work.Because the centre of helical fibre does not have elastic support, just can avoid influencing hardness with self material aging because of elastic support is subject to environment temperature, optical fiber also is subjected to the influence of support body material firmness change and influences its stability.Each circle of optical fiber is gone up or is all had a position or several positions to be fixed on the support component on several circles at interval, can guarantee that optical fiber is maintained fixed state better, can avoid the operate as normal effect of the motion effects optical fiber between the fiber turns.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
