This paper describes a microbend displacement sensor with high sensitivity and wide dynamic range designed on the bases of multimode sensor-oriented fiber. A number of high sensitive sensors have been designed on the basis of microbending induced mode coupling of core to clad modes. Usually these sensors need very accurate alignment of input end face with light source for selective mode excitation. We propose a modified sensor configuration based on microbending induced mode coupling.
