Development of the Composite-Type Optical Fiberscope for Medical Use

A composite-type optical fiberscope was developed for maintenance research and development of nuclear facilities by National Institutes for Quantum and Radiological Science and Technology (QST). It can coaxially deliver both a high-energy laser beam for micro processing and an image from processing targets. At present, we are developing a minimally invasive laser treatment device based on this technology and are expanding into the medical field. This paper introduces these medical applications.
