Abstract
An optical system for producing stereoscopic imaging of a subject. The system includes an objective lens for producing an image of the subject, and right and left ocular lenses for viewing the image through right and left eyes, respectively. A polarizing filter device positioned near the objective lens divides the image produced by the objective lens into left and right perspective components characterized by different polarization directions. Right and left polarizing filters positioned near the right and left ocular lenses allow these right and left perspective components to be viewed exclusively through the right and left ocular lenses, respectively. One embodiment of the invention is a high-power stereoscopic microscope. Another embodiment is a single-objective binocular telescope.
