It is necessary in the optical communication system that the optical fiber are able to be connected and separated each other. The optical fiber connectors are used in the above operations. The end face of the optical fiber is polished and processed at the fixed curvature. If the configuration of the processed optical fiber is good, the optical fibers can be connected with small return loss. In this study, the method for measuring the end shape of the optical fiber easily is developed using the scattered beam from the processed end face of the fiber.
