Embodiment Construction
[0047] The present invention will be further described below with examples in conjunction with the accompanying drawings, but the protection scope of the present invention should not be limited by this.
[0048] The scheme of distributed optical fiber white light interferometric sensor array using unbalanced Michelson interferometer to realize interrogation structure, such as Figure 7 shown. It can be seen from the figure that the distributed optical fiber white light interference sensor array is composed of an optoelectronic device 1 , an unbalanced Michelson interferometer 2 , a single-mode connecting optical fiber 3 , and a serial sensor array 4 . The optoelectronic device 1 is composed of a low-coherence broadband light source 111, a three-port circulator 121 and a photodetector 131; as Figure 5 shown. The unbalanced Michelson interferometer 2 is composed of a coated optical fiber reflection end 211, a scanning mirror 221, a self-focusing lens 231, and a 3dB optical fi...
