Abstract
The yielding and displaying of the 3D images of object have been investigated for many years. The methods of designing non-spherical or complicated wavefront are important for fabrications of different optical elements with low aberrations, and also very useful for the synthesis of rainbow holograms of the 3D true-color objects. The display of 3D wavefront can be realized by several methods. In this paper the technique and system of holographic synthesis of computer designed-3D wavefront are described. The 2D amplitude distribution of light wavefront of object in the recording plane can be created by computer 3D image design and by sampling the wavefront in the angles. Then, these amplitude distributions after modified by computer are output into the holographic recording systems by means of high resolution liquid crystal display (LCD) plate to form the synthetic holographic master. The master is converted into image-plane rainbow hologram in the holographic systems. The advantages of the technique, compared with the CGH and conventional holographic method, are obvious. The LCD output is simple and fast. The wavefronts of true-color object can also be fabricated by this system. The different coding holographic gratings and elements, the true-color 3D rainbow holograms can be made successfully with the technique combined with spatial frequency-coding and color- controlling technology.
