This project addresses the problem of remote inspection of highly radioactive installations. A remote-imaging system will be constructed that employs coherent fiber optic bundles to transfer an image from a reflective telescope to a location where standard imaging techniques can be used. This approach differs from other similar approaches in the use here of hollow, fluid-filled fibers. The use of high index of refraction fluid in the fibers provides for confinement of the light in the fiber. The fluid can be continuously replenished by forcing it to flow toward the high radiation end to sweep out the fluid that has been radiation damaged. The feasibility of constructing such a system using a fiber bundle and a simple vidicon-based image acquisition system will be explored. Issues to be addressed include quality of image transfer, fluid flow rates and pressures required, and analytical projections of comparative radiation hardness.Anticipated Results/Potential Commercial Applications as described by the awardee:This approach has potential application in any area where inspection of highly radioactive installations or components is required. This includes diagnostic inspection as well as inspections that are an adjunct to other processes, such as welding and maintenance operations.
