摘要
用平行光输入２Ｎ×２Ｎ 元素阵列，采用２×２ 全息透镜阵列的虚焦点成像方式，实现了元素阵列的ＰＳ（ＰｅｒｆｅｃｔＳｈｕｆｆｌｅ，即全混洗）光互连；透镜阵列直接实现ＰＳ光互连时，成像放大率为２Ｎ，成像距离ｌＨ 与Ｎ 成线性；当在全息透镜阵列后另引入一成像透镜Ｌ时，推导的成像距离公式和系统放大率公式表明：互连的成像距离主要与成像透镜焦距有关，成像放大率主要与成像透镜焦距和全息透镜焦距之比有关。相应的实验证明了各公式的正确性。
Using a 2×2 holographic lens array and a virtual focus imaging method, PS optical interconnection of the 2D elements group is realized under the parallel light input. The virtual focus imaging PS transformation of 2N×2N input element group is directly realized by the lens array. The imaging magnifying power is 2N and the imaging distance l H varies linearly with N. When an imaging lens L is inserted behind the lens array, the deduced formulas of imaging distance relate mainly to the focal length and the imaging magnifying power relates mainly to the ratio between the imaging lens focal length and the holographic lens focal length. The experiments prove correctness of the formulas.
