Our eyes provide our brain with a pair of dissimilar images. The fusion of these dissimilar images into a single image in relief in "stereopsis." All stereoscopic imaging systems are based on this principal. The imaging system records a pair of dissimilar images simultaneously. The two images are then presented to our eyes simultaneously and in such a way that the right eye sees only the image from the right eye point of view and the left eye sees only the image from the left eye point of view.
