In this paper, we propose a fast calculation method using look-up table and wavefront-recording plane. Wavefront-recording plane method consists of two steps: the first step is the calculation of a wavefront-recording plane which is placed between the object and the hologram. In the second step, we obtain the hologram by executing diffraction calculation from the wavefront-recording plane to the hologram plane. The first step of the previous wavefront-recording plane method is time consuming. In order to obtain further acceleration to the first step, we propose high compressed look-up table method based on wavefront-recording plane. We perform numerical simulations and optical experiments to verify the proposed method. Numerical simulation results show that the calculation time reduces dramatically in comparison with previous wavefront-recording plane method and the memory usage is very small. The optical experimental results are in accord with the numerical simulation results. It is expected that proposed method can greatly reduce the computational complexity and could be widely applied in the holographic field in the future.

使用波前记录平面和三维全息显示中的查询表加速计算机生成的全息图

本文提出了一种利用查找表和波前记录面的快速计算方法。波前记录平面方法包括两个步骤：第一步是计算放置在物体和全息图之间的波前记录平面。在第二步中，我们通过执行从波前记录面到全息图平面的衍射计算来获得全息图。先前的波前记录平面方法的第一步很耗时。为了获得进一步的加速，我们提出了一种基于波前记录面的高压缩查找表方法。我们进行数值模拟和光学实验，以验证所提出的方法。数值模拟结果表明，与以前的波前记录面法相比，计算时间大大减少，并且内存占用很小。光学实验结果与数值模拟结果吻合。期望所提出的方法可以大大降低计算复杂度，并且将来可以在全息领域中广泛应用。
