Endoscope and video laser camera system therefor

Claim 1

An endoscope adapted for operation in association with an optical scanner which generates a beam of radiation tracing out a raster comprising: optical channel means comprising a bundle of coherent flexible optical fibers for forming an optical channel having a proximal end and a distal end; photosensor means comprising an elemental photodetector for generating an electrical signal having an instantaneous value proportional to the quantity of light impinging on said photodetector; beam splitter means positioned in an optical path partially defined by said proximal end for directing radiation exiting said optical channel through said proximal end to said photosensor means; and imaging means responsive to said photosensor means for forming an image of an object, so that a raster from said scanner projected on said proximal end traverses said beam splitter means and said optical channel and is projected through said distal end for illuminating the surface of an object to be examined and radiation reflected from said surface traverses said optical channel and is directed by said beam splitter means to said photosensor means.
