数码相机的高分辨率使得单镜头、单传感器的光场采集成为可能，尽管为了构建特定采集场景所需的光学元件集合，仍然需要大量的设计工作。本文探索了一种设计、制造和使用面镜阵列的流水线，简化了这一任务。管道的基础是一个交互式工具，可以自动优化镜面设计，同时向用户展示一组直观的光场质量和制造限制参数。我们研究了自动制造最终设计的两种制造工艺：一种是基于一个实体工件的数控铣削，抛光和电镀，而另一种涉及CNC切割镜面的组装。我们演示了在微距摄影场景中重新聚焦的结果。此外，我们观察到传统的摄影参数在面镜阵列设置中发挥了新的作用，并讨论了它们的影响。
The high resolution of digital cameras has made single‐shot, single‐sensor acquisition of light fields feasible, though considerable design effort is still necessary in order to construct the necessary collection of optical elements for particular acquisition scenarios. This paper explores a pipeline for designing, fabricating and utilizing faceted mirror arrays which simplifies this task. The foundation of the pipeline is an interactive tool that automatically optimizes for mirror designs while exposing to the user a set of intuitive parameters for light field quality and manufacturing constraints. We investigate two manufacturing processes for automatic fabrication of the resulting designs: one is based on CNC milling, polishing, and plating of one solid work piece, while the other involves assembly of CNC‐cut mirror facets. We demonstrate results for refocusing in a macro photography scenario. In addition, we observe that traditional photographic parameters take novel roles in the faceted mirror array setup and discuss their influence.
