An etched calcite square-wave retarder is designed, fabricated, and demonstrated as an illuminator for an interlaced polarization computer-generated hologram (PCGH). The calcite square-wave retarder enables alternating columns of orthogonal linear polarizations to illuminate the interlaced PCGH. Together, these components produce a speckled, tangentially polarized PCGH diffraction pattern with a measured ratio of polarization of 84% and a degree of linear polarization of 0.81. An experimental alignment tolerance analysis is also reported.
设计、制作并展示了一种蚀刻方解石方波延迟器，作为用于交错偏振计算机生成全息图（PCGH）的照明器。方解石方波延迟器使正交线性偏振的交替列能够照亮交错的PCGH。这些组件共同产生了一个有斑点的、切向偏振的PCGH衍射图案，测量得到的偏振比为84%，线性偏振度为0.81。还报告了实验对准公差分析。
