Abstract:
A 3-D viewing system with which multiple viewers can view electronic display images of an object while sharing an optical objective, and wherein at least one of said multiple viewers may change his angular position around the optical objective and head tilt orientation while maintaining a moveable electronic display unit in position for viewing, said system comprising:an optical objective that is shared among viewers of the 3-D viewing system; an image detecting unit that detects left and right images having different perspectives; a moveable electronic display unit that displays images which have been captured by the image-detecting unit; and means to change images that are displayed by the moveable electronic display unit in response to a change in location and tilt orientation of the moveable electronic display unit, wherein the means to change images includes an arm that is rotatable about the optical axis of the optical objective, said arm supporting the moveable electronic display unit, a beam-splitting prism, and two apertures that select light which has been reflected from a surface of the beam-splitting prism, said two apertures passing light to the image detecting unit; detectors for detecting the location and left-right tilt orientation of the moveable electronic display unit; and a changing means for changing the location and tilt orientation of the image detecting unit in response to a change in location and tilt orientation of the moveable electronic display unit.
