| Abstract: | The microbend fiber optic sensor is one kind of intensity modulation sensors. It utilizes intensity loss resulting from optical fiber bending to measure change of environmental parameters, such as pressure, temperature, acceleration,strain,flow, and speed. The principle and characteristics of the microbend fiber optic sensor are simply introduced. The development and practical applications of these sensors, domestic and abroad, are discussed in detail. Finally,the limitation of the microbend fiber optic sensor is analysed. |
