“…However, a huge computing load and the expression of diverse types of virtual objects are problems that need to be addressed in CGH [5][6][7][8][9][10] . Recently, the improvement of programmability of the graphics processing unit (GPU) decreases the masses of computation in CGH [11][12][13][14] , but it is not easy to implement different types of virtual objects like traditional computer graphics (CG) techniques by conventional methods for calculating CGH. Besides, some researches consider the physical phenomena effects (e.g., occlusions, refraction, and reflection) in holographic display [15,16] , but it is still inadequate for multiple requirements of reconstructing virtual objects.…”

A holographic visualization of volume data based on adjustable ray to optical-wave conversion is presented. Computergenerated holograms are generated by emitting multiple rays to sample the volumetric field. Equal interval sampling, object light wave adjustment, and information composition are sequentially performed during the march of rays. The program is accelerated in parallel to reduce the total time, and the reconstructions are dynamically adjusted to express different parts of an object. Optical experiments verify that the proposed method can holographically reconstruct the surface and interior information of objects.

A practical method for dynamic color holographic display by using a computer-generated hologram (CGH) with a high space-bandwidth product is proposed, and a dynamic color holographic display system is designed by a space-division method. First, three primary color CGHs of different frames from a color movie are fabricated on holographic recording material by a self-made CGH microfilming system. Secondly, the CGH is fixed on an X-Y moving stage, which is controlled by the system in order to bring the CGH to the appointed position. Thirdly, three primary color lasers are used to reconstruct the CGH. The switch of the lasers is controlled by the system synchronous with the X-Y moving stage. The color video with high quality can be obtained after filtering the three primary color reconstructed wavefronts. The experimental results demonstrate that the proposed dynamic color holographic display method is effective. It has practical application value in high-quality CGH display.
