Abstract

The relationship between bend losses in plastic optical fibers and bend radius is analyzed theoretically.The mathematical model of large strain measuring based on plastic optical fibers is deduced and a corresponding measurement system is established.Through experimental research

the measured values are verified coincide well with the model.Experimental results show that the strain measurement range can be up to 8 % and the system has advantages of high sensitivity and good repeatability.
