| Summary: | The review paper of D-type optical fiber sensor (OFS) based on surface plasmon resonance principle is presented. The OFS is made of a single-mode or multimode optical fiber which was polished as a D-shape fiber and coated with an Au-film on its plane surface. The test medium could be liquid or gas and directly contacted with the sensing surface of the sensor. There are three measurement methods in this paper, such as, the phase, intensity, and relative spectrum methods. The best resolution of the refractive index measurement in these three methods is in the region of 10-5 ~ 10-6 (RIU: refractive index unit).
