Quantitative analysis of a primate photoreceptor lattice shows that the foveal lattice is a highly regular hexagonal structure with a positional correlation length of at least 130 photoreceptors. This result indicates that the photoreceptor lattice is not sufficiently disordered to prevent aliasing in the fovea, but rather could provide the metric with which the visual system determines spatial separation even for tasks involving hyperacuity .
对灵长类动物光感受器晶格的定量分析表明，中央凹晶格是一种高度规则的六边形结构，其位置相关长度至少为130个光感受器。这一结果表明，光感受器晶格的无序程度不足以防止中央凹出现混叠现象，相反，它可能为视觉系统提供一种度量标准，即使对于涉及超敏锐度的任务，视觉系统也能据此确定空间分离。
