ABSTRACT:
A simple and compact image enhancement system for industrial and medical fiberscopes including in each case adjacent each of opposite ends of the fiber bundle of a fiberscope, a plane parallel optical image transmitting plate and means for oscillating the plate about an axis normal to the fiber bundle axis. With one plate transmitting optical images to one end of the fiber bundle and the other plate transmitting the images away from the opposite end of the bundle, ultimate image enhancement and bundle blemish suppression is accomplished by synchronous oscillation of the two plates.
