摘要
Two different methods from graphic processing unit （GPU） and central processing unit （CPU） are proposed to suitably optimize look-up table algorithms of computer generated holography （CGH）. The numerical simula- tions and experimental results show that we can reconstruct a good quality object. The computation of CGH for a three-dimensional （3D） dynamic holographic display can also be sped up by programming with our proposed method. It can optimize both file loading and the inline calculation process. The phase-only CGH with gigabyte data for reconstructing 10 MB object samplings is generated. In addition, the proposed method effectively re- duced time costs of loading and writing offline tables on a CPU. It is believed the proposed method can provide high speed and huge data CGH for 3D dynamic holographic displays in the near future.
