摘　　要：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.
