空间光调制器（SLM）的显示性能导致了电子全息术中的一个问题，即再现的三维物体尺寸很小。虽然已经考虑了使用多个SLM来增大尺寸的方法，但是它们通常具有由于相邻SLM之间的差距而丢失3D对象的某些部分或者3D对象失去垂直视差的问题。本文提出了一种解决这一问题的方法，通过将包含透镜阵列和其他组件的光学系统定位在多个SLM的前面。我们使用一个光学系统和9个SLM来构建一个相当于SLM的大约74，600，000像素的设备，并使用它来重建具有63 mm图像尺寸的水平和垂直视差的3D对象，而不会丢失3D对象的任何部分。(C)2012美国光学学会
One problem in electronic holography, which is caused by the display performance of spatial light modulators (SLM), is that the size of reconstructed 3D objects is small. Although methods for increasing the size using multiple SLMs have been considered, they typically had the problem that some parts of 3D objects were missing as a result of the gap between adjacent SLMs or 3D objects lost the vertical parallax. This paper proposes a method of resolving this problem by locating an optical system containing a lens array and other components in front of multiple SLMs. We used an optical system and 9 SLMs to construct a device equivalent to an SLM with approximately 74,600,000 pixels and used this to reconstruct 3D objects in both the horizontal and vertical parallax with an image size of 63 mm without losing any part of 3D objects.
