Abstract
This paper has completed the theoretical modeling of the cured surface reflection RIM-FOS under the typical optical fiber bundle structure. Firstly, the modeling of the fiber’s axial symmetry distribution structure is made by analytical method to get the intensity modulation function M. Then the modeling of the fiber’s coaxial distribution structure is made by analytical method to get its intensity modulation function M. Finally, the simulation experiment about the mathematical model of the two typical optical fiber beam structure is conducted to get the corresponding P- M curve when the variables d, r, ???change. The simulation results show that the relationships between the variable d, r, ???and the received light intensity under different fiber bundle structures indicate that the calculation results of the mathematical model are in conformity with the actual situation. Finally, it is concluded that detection range is similar to the detection sensitivity under the two typical optical fiber bundle structures, which provides a good theoretical basis for practical design of RIM-FOS.
