A low-drift fiber-optic sensor system, consisting of 24 regenerated fiber Bragg gratings (RFBG), equally distributed over a length of 2.3 m, is presented here. The sensor system can monitor spatially extended temperature profiles with a time resoluti

Regenerated fibre Bragg gratings are formed when specially pre-treated seed gratings are heated up to several hundred degrees centigrade. During this process, the fibre Bragg grating (FBG) reflectivity vanishes and regrows, forming a regenerated grat

Here, we describe a method for producing locally micro-structured fiber Bragg gratings (LMFGB) by fs-laser machining. This technique enables the precise and reproducible ablation of cladding material to create circumferential grooves inside the cladd

Two application examples of RFBG sensor arrays that are intended for high temperature profile measurements in chemical reaction vessels and in a gas turbine exhaust duct are described. The array for the chemical reaction vessel includes four sub-arra

A new iterative matrix algorithm has been applied to improve the precision of temperature and force decoupling in multi-parameter FBG sensing. For the first time, this evaluation technique allows the integration of nonlinearities in the sensor’s te

A locally micro-structured fiber Bragg grating (LMFBG) was manufactured by forming a circumferential groove in the middle of a type I fiber Bragg grating (FBG). The groove was directly ablated using a fs-laser and had a length of 86μm, a depth of 27

An automated fs-laser machining procedure was developed to engrave circumferential grooves into the cladding of optical fibres. The grooves are positioned centrally to type I fibre Bragg gratings (FBG) and form locally micro structured FBGs. The groo
