Paper Abstract

Based on the bending loss theory of polymer optical fiber, mathematical model of polymer optical fiber large strain sensing is established. Three different polymer optical fiber large strain sensitive structures are designed. And a corresponding intensity modulated polymer optical fiber large strain sensing system is established. The different aspects of properties of three designed sensitive structures are researched and compared by the means of ANSYS software simulation and experimental system. Experimental results show that the designed sensor of b-type structure is a large strain sensor, which has good performance. The b-type sensor's strain measurement range has up to 20%, moreover, its non-linear error is approximate 1.4%, and the system has advantages of high sensitivity.
