Abstract
Światłowodowy czujnik zgięć zawiera wielordzeniowe włókno mikrostrukturalne posiadające co najmniej trzy rdzenie, którego to rdzenie umieszczone są w płaszczu quasi-periodycznych otworów powietrznych asymetrycznie umieszczonych wokół rdzeni, otwory powietrzne wypełnione są dowolnym gazem, w szczególności powietrzem, ciałem stałym lub cieczą, a światłowód połączony jest w celu wprowadzenie/wyprowadzenie sygnału do każdego rdzeni, odpowiednio z co najmniej jednym źródłem światła (1) i co najmniej jednym detektorem. Przedmiotem zgłoszenia jest również sposób pomiaru zagięć.The fiber-optic bend sensor comprises a multi-core microstructural fiber having at least three cores, the cores of which are placed in a jacket of quasi-periodic air holes asymmetrically placed around the cores, the air holes are filled with any gas, in particular air, solid or liquid, and the optical fiber is connected by to input / output a signal to each cores, with at least one light source (1) and at least one detector, respectively. The subject of the application is also the method of measuring bends.
