Abstract

A composite-type optical fiberscope which has furthered technical development in Japan Atomic Energy Agency (JAEA) is a special fiberscope which can treat both a high energy laser light and image information [1]. This composite type optical fiberscope was born as a specific tool which is useful for the maintenance technical development in a nuclear fusion reactor and a large-sized nuclear installation [2][3]. This fiberscope is useful in narrow parts, such as a fuel bundle of reactor internal, and piping of a heat exchanger. Since this technology has high flexibility, at the present, the application to the medical field is under promotion as diagnostic and treatment equipment. In this report, the basic structure of a composite-type optical fiberscope and the example of the medical application are introduced.
