交感量子化--全息图量子化的一种新方法
Sympathetic quantisation -- a new approach to hologram quantisation
摘要：
空间光调制器通常只能调制入射波前的相位或振幅，只有有限数量的离散值可用。这通常在计算机生成的全息算法中通过在所谓的量化期间将全息图像素值设置为最接近的可实现值来解决。交感量化是这种最近邻方法的替代方案，其考虑了潜在的衍射关系，以便获得显着改善的量化后性能。本文介绍了交感量化的概念，并提出了一个简单的实现，软交感量化，这是改善均方误差和结构相似性指数误差指标的50%的考虑情况下的单变换算法。
英文摘要：
Spatial light modulators can typically only modulate the phase or the amplitude of an incident wavefront, with only a limited number of discrete values available. This is often accounted for in computer-generated holography algorithms by setting hologram pixel values to the nearest achievable value during what is known as quantisation. Sympathetic quantisation is an alternative to this nearest-neighbour approach that takes into account the underlying diffraction relationships in order to obtain a significantly improved post-quantisation performance. The concept of sympathetic quantisation is introduced in this paper and a simple implementation, soft sympathetic quantisation, is presented which is shown to improve mean squared error and structural similarity index error metrics by 50% for the considered case of single-transform algorithms.
