https://www.atgrating.com/products/chirped-fbg.html

The grating period of Chirped FBG is not constant, but varies along the axial direction. Different grating periods correspond to different Bragg reflection wavelengths, and incident light of different wavelengths is reflected at different positions of the chirped fiber grating, so that the light of different wavelengths will produce an optical path difference after being reflected by the chirped fiber grating. Using this effect of linearly chirped fiber bragg grating , the dispersion compensation of different wavelength signals in long-distance fiber communication can be effectively realized.

Fiber Bragg gratings are very sensitive to stress and temperature. No matter whether the FBG is subjected to stress or the ambient temperature changes, it is reflected in the fiber grating that the grating pitch has changed, that is, the fiber grating sensor has corresponding strain. This means that when you want to use FBG strain sensors for accurate testing, you must consider whether the ambient temperature has changed, you must deduct the effect of temperature on the reflected wavelength from formula Strain(μɛ)=((λS-λS0）-（λT-λT0）*KT)/Ks, that is to say, let (λT-λT0)=0 or the value of (λT-λT0) is numerically known, this process is called FBG Temperature Compensation for Strain sensors.

Types of FBG Strain Sensor
FBG Strain Sensor MS-01/MST-01
Mountable Strain Sensor MS-01 made of stainless steel, the sensing part adopts elastic structure, and the mounting base is a separate component, which can be easily installed.

FBG Strain Sensor MS-02
Mountable Strain Sensor MS-02 made of stainless steel, elastic structure of the sensing part fixes the optical fiber in the stainless steel plate in the form of non-glue, which can be used permanently.

FBG Strain Sensor ES-01&EST-01
Embedded Strain Sensor ES-01 is used for strain detection of structural safety, such as the internal strain detection of concrete in bridges, reservoirs, dams, highway tunnels, and other buildings.

FBG Strain Sensor MST-03
Mountable Strain Sensor MST-01 adopt the technology of temperature compensation, two FBG inside the housing, which can eliminate the influence of the temperature from strain monitoring.

Principle and Method of Temperature Compensation for FBG Strain Sensor
The best way for AtGrating to compensate the temperature for the FBG strain sensor is to inscribe double gratings in one fiber, and then package it into the FBG strain sensor with temperature compensation, one FBG is used to measure the strain, and the other is used to measure the strain. Since the strain FBG and temperature FBG are in the same temperature environment, the temperature value measured by temperature FBG can be regarded as the temperature of strain FBG. Hence we can deduct the influence of temperature on the reflected wavelength from formula Strain(μɛ)=((λS -λS0)-(λT-λT0)*KT)/Ks, so as to obtain an accurate strain change value.
