The 3-dimensional(3-d) frequency [horizontal-vertical-temporal frequency] domain can be understood easily and directly by the newly proposed SZB(Spherical Zone Ball), which is the direct extension of the 2-d CZP(Circular Zone Plate) to the 3-d one. This paper also proposes the direct-observing method of the 3-d frequency characteristics.
