The invention belongs to the technical field of optical fiber sensing, and in particular relates to a surface plasmon resonance optical fiber sensor and a detection method. The surface plasmon resonance optical fiber sensor includes an optical fiber body and a metal film arranged on the end face of the optical fiber body. and concentric holes, the disk is arranged in the concentric holes, and the concentric holes penetrate through the end face of the metal film. The surface plasmon resonance optical fiber sensor of the present invention can be detected by inserting the sensor probe into the object to be measured, and compared with the sensor in the prior art, the sensitivity and detection accuracy are improved, and the optical fiber sensor has a simple structure, strong anti-electromagnetic interference capability, and a package size. Small, has broader application prospects. |
