| Abstract: | Wavelength-shift detection is the key technology of fiber Bragg grating sensor. The four sorts of wavelength detection schemes are introduced in detail, that are broadband light source/broadband filter or edge filter, broadband light source/tunable filter, broadband light souree/interferometrie detection and tunable narrowband light source/broadband receiving. Furthermore,the basic operation principles of seven kinds of wavelength-shift detection methods are analyzed,and their characteristics are discussed respectively. |
