| Abstract: | Proposed a kind of interrogation system based on optic fused fiber coupler is proposed.An over coupled fiber coupler is made and its transmission spectrum is researched by relevant experiments.Also the principle of demodulation with this over coupled coupler is discussed.Optic fiber grating sensor demodulation using over coupled coupler experiment is carried on and good response is obtained.Low-cost and a wide scope of 10 nm demodulation range are achieved by this interrogation method. |
| Keywords: | fiber grating fused coupler over coupled fiber coupler demodulation |
