We demonstrate the creation of a three dimensional (3D) lattice of focus spots using a 3D Dammann grating structure. Such a 3D lattice of focus spots can be used for probing 3D structures or for creating 3D photonic crystal structures in optically sensitive media. Experimental results are included where the patterns are encoded onto a programmable liquid crystal display. We demonstrate the generation of five planar arrays each having 6×6 points surrounding another set of four planar arrays each having 5×5 points with a single pattern.
我们展示了利用三维达曼光栅结构创建焦点的三维（3D）晶格。这种焦点的三维晶格可用于探测三维结构或在光学敏感介质中创建三维光子晶体结构。文中包含了将图案编码到可编程液晶显示器上的实验结果。我们展示了生成五个平面阵列，每个平面阵列有6×6个点，围绕着另一组四个平面阵列，每个平面阵列有5×5个点，且这些都由单个图案构成。
