NOVEL OPTICAL FIBERS: Draw-tower process creates high-quality FBG arrays

However,because of the significant investment required in the draw tower and associated measurement equipment, the manufacturing process has only recently become viable. This development has resulted in increased industry use of sensors that rely on FBG’s in optical fibers.
