A new method of creating three-dimensional images with a grating pattern which consists of many small diffraction gratings is presented. The grating image gives its holographic display a very interesting feature, showing brilliant multi-color and moving effects. Conventional grating images are two-dimensional (2-D) patterns, but by this method a three-dimensional (3- D) image is generated. The basic principle of this method is parallax panoramagram, and the composed image is similar to the holographic stereogram. This type of image looks much brighter and clearer than the current holographic stereogram, because it consists of very simple gratings. The grating pattern is made by using an electron beam writing system. The system has the capability to change the direction and spatial frequency of the grating. In this paper, the principle and the development of the system for the new 3-D image is described.
