Abstract
We present a new method for solid object 3-D imaging which can control the emitting diagram of each image point and can be applied in volumetric displays. A new method is based on the fact that the visibility of each point of the 3-D object or scene can be described in the terms of point's emitting diagram. It was found that the amount of information for the emitting diagram in general has the same order of magnitude as that for sampled hologram. The emitting diagram control can be applied to many different types of volumetric display with use of means like spatial filters. Unlike the electroholography, the method provides 3-D positioning of image points and emitting diagram forming separately. So in special cases, it allows us to reduce significantly information amount. Experimentally, we obtained a color stereoscopic image with a number of resolvable perspective views, distributed within 30 angular degrees using only two 2-D images and a moving shield as the diagram former.
