Abstract

Video-stereoscopic-image-producing system and a method for using the system is taught. The system is disclosed in conjunction with medical applications, specifically, in an embodiment useful for examining eyes. The system includes a binocular viewer for producing a pair of input images of an object which may be viewed to produce a stereoscopic image of the object. Video cameras are provided to receive a pair of images so produced and for producing, in turn, video signals representative of those images. An interface is provided for optically joining the video cameras to the binocular viewer. Video digitizing and freeze-frame equipment is joined to the cameras for generating a video display of the pair of input images and a stereoscopic viewer is provided for use with the video monitor for providing stereoscopic viewing of the displayed images by an observer. A method of using the system is taught which includes the steps of producing a pair of images of an object which may be viewed stereoscopically to produce a stereoscopic image and converting the images into a video signal representative of the images, transmitting the video signal over transmission medium to a remote location, r…
