Abstract

A hand-held 3-D imaging system which incorporates the stereoscopic imaging system within a pair of binoculars. Each telescope optical system has a first optical system, a second optical system, and a third optical system. The first optical system allows for external magnified stereo viewing of an object. The second optical system allows for recording the magnified stereo image(s) viewed through the optics of the first optical system. The third optical system allows for reproduction of the magnified stereo image(s) captured by the second optical system. The hand-held 3-D imaging system further includes record and playback modes that are activated by switches connected to electronic processing circuitry located within the frame of the binoculars. The imaging system can also be designed to interact with external memory devices and/or displays.
