Note (General): An optical fiber sensor system using the radius of curvature changes has been proposed. The system can be laid on the face of a target building construction. Experiments on the proposed technique showed that the graded-index polymer optical fiber (G1-POF) had sensitivity to radius of curvature changes and the advantage of mechanical flexibility suitable for sensing a small radius of curvature. Optical losses by changing the radius of curvature in the graded-index optical fiber have been calculated with either simple methods that lack sufficient accuracy or others that require a large capability to calculate. A calculation algorithm that allows the quantitative evaluation of optical losses in bending fiber by a computer with a reasonable performance has been invented, and it has been adopted to a newly developed simulator. The simulation result was comparable to experimental data in the range of 2 dB, in which the radius of curvature is several mm.
