LPFG is formed by the large-scale high output sources of light such as excimer laser beams, but it usually becomes the problem that transference in this technique being expensive and the fiber which have been laid is difficult. The technique that can solve the problem includes the LPFG formation method by the mechanical instruction. It is intended that I constitute LPFG optical sensor using acrylic resin formed of 3D printer to be cheaper, and to realize mechanical technique in this study.
