6U THREE-DIMENSIONAL MOTION PICTURES point in the image space and form there a conjugate focal point of the object point L This effect is obtained through the phenomenon of refraction and by the use of convergent lenses or systems of lenses. A lens is a piece of refracting material, most usually glass, by which the path of the light rays may be controlled by means of both the quality of the material of which the lens Is made and the shape of the refracting surfaces which serve as the bound ary of the lens. By tracing the path of at least two of the rays emitted by an object point situated either on the axis of the lens or outside of it and passing through the refracting system, we should, in order to obtain a perfect Image of the object point, find them to converge at exactly the same point in the image space where a conjugate of the object point would therefore be formed. In other words a perfect image of that object point should be formed by the meeting of the refracted rays and such image would be much more luminous than the image of the same point of the same object obtained through a pin hole, because of the concentration of a great number of light rays Instead of the direct effect produced by the rays of the extremely small pencil of .light limited by the'size of the pin hole.
