Optical design process of a human eye inspired lens

Bio-inspired optical design can be described as a conscious decision in the design process to take inspiration from physical adaptation that were brought up by natural selection. The usual goal is to introduce non-conventional techniques or material in order to achieve better performance or novel applications. However, when the target is to imitate closely the form-factor, appearance and optical properties of a biological system, new requirements are added to the design process and new problems arises. In this paper, we will expose the design of an optical system that draws most requirements from both the optical properties and the form-factor of the human eye. However, contrary to human eye models, the main requirements for this project is to make a realistic design which can be assembled as a prototype. The design process will be laid out, by firstly introducing system requirements and various performance targets that comes from the bio-inspired design. The constraints associated with using entrance pupil's appearance as a requirement will be presented. This paper will also specifically be looking at distortion as a solution for modulating resolution throughout the field of view and as a tool to aid in those novel problems.
