Abstract

This paper describes development of a biologically-inspired wide-angle fovea lens well-known as a significant part of the bio-mimetic vision sensor. The authors develop a micro wide angle fovea (WAF) lens suitable for a board lens camera with a 1/3 inch imaging chip. The prototype of this Micro WAF lens has a smaller diameter and length, i.e., 8mm × 15mm, than half of the WAF lens the author produced formerly, i.e., 16mm × 32mm, while its central field of view (FOV), we call fovea, has much higher resolution, i.e., its projected image is more highly-distorted than the former WAF lens. The central FOV is about 10 percent of the entire FOV inside an incident angle of 2.5 degrees in Micro WAF lens, while it is about 10 percent inside an incident angle of 10 degrees in the former WAF lens. We focus mainly on determining its specification as the 1st step of a lens design procedure and discussing results simulated using a lens design software.
