Range finding fiberscope

A range finding instrument comprising:

• a pair of image-conducting bundles of optical fibers each having a distal image-receiving face and a proximal image-emitting face, said proximal faces being juxtapositioned and said distal faces being fixedly spaced a predetermined distance apart in a first plane with axes thereof extending substantially parallel to one another;
• light deflecting means in aligned spaced relationship with a first of said distal faces, said deflecting means intersecting the axis of said first face, the point of said intersection being in a second plane parallel to said first plane, said second plane establishing a reference from which range finding measurements may be made;
• a first objective lens means axially aligned between said deflecting means and said first distal face for focusing an image of a remote object upon said first face;
• second objective lens means axially aligned with the second of said distal faces for focusing an image of said same remote object upon said second face, centering of said image on said second face being accomplished by movement of said instrument;
• means for independently angularly adjusting said light deflecting means relative to said first distal face to center said image of said remote object upon said first distal face;
• and
• means for determining extent of angulation of said light deflecting means for determination of range of said object from said second plane.
