ABSTRACT:
An endoscope for stereo-optically viewing an object comprises a tubular insertion portion characterized by a pair of adjacent asymmetric optical systems including a primary imaging channel and a secondary imaging channel. Associated with each channel is a solid state electronic imaging means positioned to receive the images relayed by primary and secondary image-relaying means. The optical portion of the primary channel comprises a relatively large objective lens system and a primary image-relaying means designed to provide sharply focussed first images. The optical portion of the secondary channel comprises a relatively small diameter objective lens system and a secondary image-relaying means designed to relay enough light and image information to provide an acceptable stereoscopic capability.
