Abstract
A fiber optic endoscope which uses a bundle of coherent fiber to convey both an optical image in one direction and illumination light in the other direction. A fraction of the optical fibers are used for the illumination, and others of the fibers are used for the image. Notched fibers can be used for the illumination.
