论文摘要
空间光调节器通常只能调节入射波前的相位或幅度,只有有限的离散值可用。这通常在计算机生成的全息算法中通过将全息图像素值设置为所谓的定量期间最接近的值。交感神经定量是这种最近的邻居方法的替代方法,该方法考虑了基本的衍射关系,以获得显着改善的定量后绩效。本文介绍了交感定量的概念,并提出了一个简单的实施,即软性交感定量,这被证明可以将平方误差和结构相似性指数指标指标提高50%。
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.
