Abstract

Two types of 3D displays producing a volume image in a large hall are considered. The image is consisting of a set of horizontal or vertical scene slices. It is suggested for a slice scanning in vertical direction or along the depth to use a little light deflectors mounted in an observer glasses. That decreases significantly the requirements to 3D monitor elements. Two deflectors for this private optic frame scanning are considered: one based on a scanning galvanometer and other is a rotating disk on the bases of Fresnel prisms. The output images of these deflectors do not depend on a glasses orientation in the horizontal surface and therefore the observers may move free in the hall. This is an advantage of the suggested method as compared with the stereo methods.
