Ultrathin camera inspired by visual system of Xenos peckii

This paper reports ultrathin digital camera inspired by the visual system of Xenos peckii, which is an endoparasite of paper wasps. Males of the Xenos peckii have an unusual visual system that consists of a large lens and multiple photoreceptor cells. This optical scheme exhibits distinguished benefits in resolution and sensitivity. Xenos peckii vision inspired camera consists of microprism arrays, microlens arrays, and aperture arrays. The microprism arrays were implemented by using a ball lens and backside exposure with prepatterned metal mask. And the light absorbing structures were formed between the microprism arrays using black polymer. Each channel of the camera detects different part of the total field of view, and captured partial images are reconstructed in the image processing step.
