ABSTRACT:
A pattern projecting system for automatic focusing endoscopes arranged so that light from a pattern of pre-determined shape is imaged on the end face on the observer side of an image fiber arranged in an endoscope, is reflected by the object after passing through the image fiber and objective, inversely transmitted by the image fiber and is detected by a detector after going out from the end face on the observer side of the image fiber. An automatic focusing means is arranged to automatically move the objective along its optical axis, based on the output of the detector.
