Description
When the spectator looks at perspective views through the lens of the viewing machine, an illusion of recession is produced. In principle, a similar illusion of distance can he achieved simply by using a single, detached convex lens which is larger than the distance between two human eyes (at least ten centimetres).
When this lens is held just in front of the eyes, the spectator is looking at the perspective view through its two edges which function like two prisms. Light rays bouncing off the print are refracted in such a way that they enter the eyes in a parallel direction. The brain interprets the incoming parallel images as a single image seen from a great distance. The important function of the lens in the optical machine is not its magnification but its creation of an illusion of depth in binocular vision. This stand is made of Oakwood and is in good working condition.
