It learns characteristic and has an impact (light scattering of inside of optical fibre has temperature characterisitic), biography is known by the variation of detection fiber optical characteristics
The temperature of the photosensitive upper a certain section of optical fiber of fibre.High power narrow band light pulse is sent into optical fiber by distributed optical fiber temperature sensing system, is visited
It surveys the scattered light intensity returned to change with time, so as to entire continuously on fiber lengths, with the continuous function shape of distance
Formula detects the temperature value of the upper each point of fiber lengths variation.Distributed optical fiber temperature sensing system have it is passive, distributed, from
The advantages that positioning, the application in engineering are more and more extensive.
On the one hand, since the distance that optical fiber sensing system is positioned is that the light velocity of foundation reflected light and the product of time are obtained
, therefore, detected distance is actually length of the light source to the optical fiber itself between test point in optical fiber sensing system.
Since after sensor fibre arranges, the parameter that computer needs a certain section of optical fiber to measure is corresponding with spatial position, that is, knows light
Which place the parameter event that fibre measures is happened at, and this can not come according to the fiber lengths laid from central machine room to scene into
Row is accurate corresponding.For a user, more concerned be test point spatial position, it is therefore desirable to have to spatial position and optical fiber
Length is demarcated.
On the other hand, with the extension of Fibre Optical Sensor temp measuring system usage time or the increase of fibre junction point, sensing
A degree of decaying or drift can occur for the optical element in system, at this time in order to maintain the accuracy of system thermometric, it is also desirable to
Optical fiber temperature measurement system is corrected.
In addition, also have the detection that a kind of distributed optical fiber sensing system is used for other physical parameters now, such as stress
Detection, principle are：When applying stress on optical fiber, the optical characteristics of optical fiber can change.So by detecting its optics spy
The variation of property and know the stress intensity on sensor fibre suffered by a certain section of optical fiber.This optical fiber sensing system has distribution
With self-positioning feature.
However, the problem of being faced with the above-mentioned optical fiber sensing system for detecting temperature is identical, due to optical fiber sensing system
The distance positioned is that the light velocity of foundation reflected light and the product of time are obtained, and therefore, is detected in optical fiber sensing system
To distance be actually length of the light source to the optical fiber itself between test point.For a user, more concerned be test point
Spatial position, therefore be also required to demarcate spatial position and fiber lengths there are one method.
