Volume imaging, holography, and conoscopy are methods of recording three-dimensional images. We show that the dependence of the resolution cell size on distance is different for each system and determines the gray-level requirements of the detection and recording system in each case. Expressions are developed for the total number of resolution cells in the observable object volume. This is of interest in determining the total amount of data that must be processed by an electronic imaging system. Tables of performance figures are given for ideal and realistic conditions.
