Optical Fiber Bragg Grating Center of Wavelength Detection Filter Algorithm

摘要：

There are various optical noises in Fiber Bragg Grating (FBG) sensing system inevitably, these noises severely limit the accuracy of detection wavelength, and also bring many difficulties to wavelength detection. In practical applications, fiber grating systems are often connected to multiple FBG sensors; there are many reflection points, which make the noise situation more complex. In order to reduce these noises, we can use hardware to reduce the noise impact, but it will raise the costs or bring inconvenience. This paper presents a selection method, which can effectively reduce the noise impact of digital signal processing techniques, such as filtering and other methods. The proposed method is not only cost saving, easy to implement changes, but also has strong versatility.
