Deep understanding of biological superposition compound eye provides great opportunities in developing imaging systems with features beyond current planar detector array based imaging devices. However, artificial superposition compound eyes are designed on the basis of a planar detector array and that subsequently leads to the complex optical design and degradation of imaging quality inevitably. We propose a single-pixel superposition compound eye (SPSCE), whose imaging resolution has been improved two orders of magnitude than the number of ommatidia without subsequent image processing. SPSCE has the ability to capture the whole acceptable image of objects even if almost one-third of ommatidia at random positions are not working, which makes it possible to operate reliably even in the damaged state. SPSCE has the capacity to image beyond the actual visual field of the target without observing directly. With only one lateral sub-eye working and deviating from the visual field of the target by 20.41, SPSCE obtains the complete and recognizable image of the target independently through the diffuse reflection optical information of the surrounding environment. The unique super-robust character of SPSCE with its super-resolution property contributes to developing anti-interference artificial compound eyes, unlocking the limit toward development of much higher imaging resolution artificial superposition compound eyes.

超分辨率超强单像素叠加复眼

对生物叠加复眼的深入理解为开发具有超越当前基于平面探测器阵列的成像设备的功能的成像系统提供了巨大的机会。然而,人工叠加复眼是在平面探测器阵列的基础上设计的,这不可避免地导致光学设计复杂和成像质量下降。我们提出了一种单像素叠加复眼(SPSCE),其成像分辨率比没有后续图像处理的小眼数量提高了两个数量级。即使随机位置的近三分之一小眼不工作,SPSCE 也能够捕获物体的整个可接受的图像,这使得即使在损坏状态下也能可靠运行。SPSCE 能够在不直接观察的情况下对目标的实际视野进行成像。只有一个侧副眼工作,偏离目标视野20.41,SPSCE通过周围环境的漫反射光学信息独立获得目标完整的、可识别的图像。SPSCE独特的超强特性及其超分辨率特性有助于开发抗干扰人工复眼,为开发更高成像分辨率的人工叠加复眼打开了限制。
