Production Process


A concept study for a bend sensor based on a fibre Bragg grating (FBG) and a compact evaluation unit for the investigated type of sensor is presented. For this, two independent measurands, one well known and one novel, are considered. The fibreoptic sensor principle is capable of resolving the radius and the direction of the bend. The measurement data evaluation principle is capable of resolving multiple distributed FBG sensors, which are present in a single fibre at different positions.
