Title:Digital Cameras with Designs Inspired by the Arthropod Eye
Author(s):Cho, Hyun Woo

Subject(s):arthropod eye camera
Abstract:The imaging system of the arthropod eye is a collection of incredibly sophisticated technologies. The digital camera mimicking the arthropod eye is a remarkable imaging device with many attractive features, such as wide-angle field of view, low aberrations high acuity to motion and an infinite depth of field. The arthropod eye uses a compound design; hemispherical array of tiny eye cells (ommatidium) operate together to assemble image perception. However, implementing the digital camera of hemispherical shape is limited with existing planar sensor technologies or conventional optics. As a solution, we used stretchable / flexible material compound optical elements with integration of thin silicon photo-detectors to deform the shape into almost fully hemispherical (about 160 degree). This project explored the materials and techniques to meet this challenge and build an electronic arthropod eye camera of curvature optics. Based on imaging test and quantitative ray-tracing-based simulations, the results indicate directions to pursue, and we expect to expand the application range.
