Paper Abstract

A new method of 3D image formation is proposed. A 3D image is generated in this case by a matrix of aspects of a 3D scene that are focused in spots. The matrix is formed by a laser scanning beam in which the aspects of the scene are introduced in consecutive order. As a result the observer sees on the screen a 2D image whose configuration changes depending on the position of the eye in such a way as if the observer examines the real 3D object. The optical scheme of AFS Display (Aspect-Focused-in-Spot Display) is presented and the mechanism of 3D image formation is considered. The results of the experiment on modeling a 3D image which is formed by a scanning spot of light that projects the aspects of the scene are given. The experiment has been carried out as applied to the case of projection of a 3D image that reproduces the horizontal parallax only. It is pointed out that the display considered is compatible with existing TV system. It is supposed that it can be used as a 3D computer display, for 3D imaging in educating, medicine, flight and car training and so on.
