Dynamic image enhancer for fiberscopes
First Claim
Patent Images
1. In a dynamic image enhancing system for fiberscopes, the improvement comprising:
- a distal image-forming objective having first and second lenses, the first of said lenses being fixed in aligned spaced relationship with one end of an image-transporting fiber bundle of a fiberscope incorporating said image-enhancing system and the second of said lenses being positioned between said first lens and fiber bundle;
means permitting pivoting of said second lens relative to said one end of said fiber bundle; and
means for effecting said pivoting in controlled oscillating fashion for causing images produced by said objective to repeatedly scan across said one end of said fiber bundle.

Abstract
A fiberscope objective having an oscillating lens element which causes images formed by the objective to scan across a receiving end of an image-transporting fiber bundle for increased image resolution and bundle blemish suppression. Synchronous scanning of the opposite bundle end renders transported images stationary for viewing.

8. In a dynamic image enhancing system for fiberscopes, the improvement comprising:
an image transporting fiber bundle, an objective lens in aligned spaced relationship with one end of the fiber bundle, at least one component of said objective being arranged to pivot about an axis perpendicular to the optical axis of said objective and means for effecting said pivoting in controlled oscillating fashion for causing images produced by said objective to repeatedly scan across said one end of said fiber bundle.
