摘要: This paper investigates experimentally the change of refractive index, due to forces such as pulling and pure bending, in an optical fiber fabricated by CVD technique. It is found that this phenomenon can be interpreted terms a simple model fiber, is, mechanically homogeneous circular rod. We compare effect refractive-index geometrical deformation on transmission characteristics. A new method based photoelasticity also proposed measure curvature distribution whose axis deformed external forces.
