Abstract

Abstract A technique for producing a three-dimensional holographic display which is updatable in real time is disclosed. A spinning lens device intercepts a two-dimensional display on a projection television receiver and transforms same into a three-dimensional holographic display in free space. The holographic display is modifiable by the control room operator and process control variables can be readily superimposed thereon.
