Direct volume access by an improved electro-holography image generator

摘要

Abstract: A CAD system with electronic holography is expected to provide ideal designing environments to feel and touch truly 3D images directly. However, interactivity and real-time computation of holographic fringe patterns are the essential requirements to realize it. This paper presents two different types of 3D images creating system. One consists of a 3D pointing device and an electro-holography system with an acousto-optical modulator which was proposed by Prof. Benton in 1989. The other consists of a 3D pointing device and an electro-holography system with a liquid crystal device. We also propose an effective method not depending on the total number of points in the scene and apply it to the designing tool by only appending points in a electro-holography system with a 3D input device.!4
