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.
