Three dimensional display based on thick holographic phase components
Abstract
In many different fields of information processing, such as medical or aerial image processing, computer aided design or manufacturing (CAD/CAM), and flight simulation or control activities, there exists an increasing need for display of true three-dimensional data. In this paper a screen is proposed that composes a three-dimensional image from information of different depth planes (image slices). The angular selectivity of holographic elements in a thick phase material (such as dichromated gelatin) is used to combine the image slices, which are projected from different directions to a three-dimensional image. This screen has a high light efficiency, uses no mechanically moving parts, and can be addressed in real time. The principle of the setup will be described, and some preliminary results will be presented.
