Conventional display systems based on integral imaging (InI) suffer from a major tradeoff between depth of field and spatial resolution. In this Letter, a new, to the best of our knowledge, a method for an InI-based light field display with an extended depth of field is proposed, where a digitally switchable multi-focal micro lens array can yield a depth of field spanning a depth range from zero to over three diopters without sacrificing either spatial resolution or form factor. A high optical performance display prototype was built and demonstrated with printed aperture arrays as a substitute for a custom-designed programmable shutter array that is still under construction.
基于整体成像（InI）的传统显示系统在景深和空间分辨率之间存在着重大的折衷。在本信中，我们提出了一种新的基于 InI 的光场显示方法，具有扩展的景深，其中数字可切换的多焦点微透镜阵列可以在不牺牲空间分辨率或外形尺寸的情况下，提供从零到超过三屈光度的景深范围。我们构建并展示了一个具有高光学性能的显示原型，该原型使用印刷孔径阵列代替了正在构建的定制可编程快门阵列。
