Abstract

PURPOSE:To enable exact conversion and detection of the quantity of the UV rays in the light propagated into an optical fiber in the form of quantity of fluorescence by incorporating a fluorescent material which emits fluoresence by sensing the light of a prescribed wavelength region into at least one layer of the multi-layered structure of the optical fiber. CONSTITUTION:The optical fiber 10 consists of a core 1 made of quartz and a clad layer 2 made of a polymer. About 1,000ppm fluorescent material is incorporated into the layer 2. The top ene and intermediate part are looped plural times and the other end face is connected to a photodetector 11. If the looped part is placed to face a flame F, the light of the flame F is made incident on the inside of the fiber 10 from one end face or the peripheral surface in the intermediate part of the fiber 10 and since part thereof passes the inside of the layer 2, the UV rays included therein are absorbed into the fluorescent material 4 and fluorescence is emitted from the material 4. The fluorescence enters not only the clad layer 2 but also the inside of the core 1, propagates in the core and is captured by a photodetector 11, by which the energy thereof is detected and the flame is thus detected.
