Abstract: A fiber optic probe is provided for use in viewing remote images, such as in vivo images in a biomedical environment or the like. The probe includes a tubular outer casing having an optical fiber of generally ring-shaped cross section, in combination with an inner fiber cable extending coaxially within the casing and defined by a coherent matrix or bundle of optical fibers. At a selected position spaced from a tip end of the probe, the inner cable passes through a gap in the fiber ring to the exterior of the casing for separate and relatively convenient coupling of the fiber ring and cable respectively to a light source and to image monitoring apparatus.
