仅位相空间光调制器用于从由Gerchberg-Saxton迭代算法计算的同轴相位全息图中再现。虽然迭代过程计算全息图的速度很慢，但我们用相当少的迭代次数就得到了足够的结果。我们已经证明，重建尺寸大于SLM尺寸的2D对象是可能的。不仅单个平面2D物体，而且不同深度的多个物体都是通过叠加其复杂的衍射图而用位相全息图再现的。位相全息图的数值再现和光学再现的结果都是令人满意的。
Phase-only spatial light modulators are used for reconstructions from inline phase holograms that are calculated by Gerchberg-Saxton iterative algorithm. Although iterative procedures are slow in computing holograms, we obtained sufficient results with a rather low number of iterations. We have shown that reconstruction of 2D objects whose sizes are larger than SLM size is possible. Not only single plane 2D objects but also several objects in different depths are reconstructed using phase holograms by superposing their complex diffraction patterns. Results of both numerical and optical reconstructions from phase holograms are satisfactory.
