Abstract
A switching apparatus for use in a stereoscopic system for producing stereoscopic image paths from a single image path. The apparatus comprises a movable member having an opaque portion disposed in the single image path, and a switching device including at least one electromagnet responsive to signals received from a synchronizer in communication with an imaging apparatus. The electromagnet imposes a force on the movable member, to move the movable member between first and second positions, in which the opaque portion is in first and second locations respectively in the single image path, to alternately define on opposite sides of the opaque portion first and second image path portions of the single image path. The first and second image path portions have first and second spaced apart centroids respectively and the sizes of the first and second image path portions and distances between centroids thereof may be adjusted or varied to vary the amount of stereopsis.
