Long Distance Distributed Strain Sensing in OFDR by BM3D-SAPCA Image Denoising

We present a long distance distributed strain sensing in optical frequency domain reflectometry (OFDR) by shape-adaptive principal component analysis Block-Matching three-dimensional filter (BM3D-S…

Elimination of Side Lobe Ghost Peak Using Wiener Deconvolution Filter in OFDR

Ghost peaks refer to these peaks on backscattering trace measured by a reflectometer similar to Fresnel reflection peaks appearing at the position of non-reflection events in optical fiber or optic…

Hybrid Sapphire Dual-Fabry—Perot-Cavities Sensor for High Temperature and R…

We presented a hybrid sapphire dual-Fabry-Perot- cavities sensor for high temperature and refractive index measurement. A double-sided polished sapphire solid wafer is connected in series with a do…

Golden Ratio Primal-Dual Algorithm with Linesearch

The golden ratio primal-dual algorithm (GRPDA) is a new variant of the classical Arrow--Hurwicz method for solving structured convex optimization problems, in which the objective function consists …

Review of Fiber Mechanical and Thermal Multi-Parameter Measurement Technologi…

In extreme environments such as abysmal sea and deep space, the characteristics of low-temperature, vacuum, electromagnetic interference will significantly affect the performance of measuring instr…

Dual-Frequency CARS Excitation Source With Two Independent-Tunable Stokes Wav…

An excitation source with two independent-tunable Stokes wavelengths is demonstrated for dual-frequency coherent anti-Stokes Raman scattering applications. Two Stokes wavelengths can be independent…
