ABSTRACT:
A stereoscopic video camera system uses a single objective lens system mounted at the distal end of a surgical endoscope. An electronic shutter is disposed within the optical path between the lens and a video camera/sensor. The shutter has left and right optical zones which are switched between opaque and light transmissive states in response to a drive signal which is synchronized both with the camera/sensor and with stereoscopic viewing glasses having switchable left and right viewing lenses.
