A true 3D image is synthesised from many 2D views of the original. The views are presented in rapid succession on a CRT whose field of view is restricted to a different zone for each view. This restriction is achieved by using optical fourier transforms which result in a 3D image that is especially sharp and clear. The display is bulky but inherently robust and flexible. It is therefore well adapted for the design of novel 3D systems.
