In this book the design of a CMOS image sensor inspired by the compound eye of insects, as well as several applications of such image sensor are presented. The sensor is able to detect polarization information using a micro-polarizer oriented at various angles and created using the metal layers in a standard CMOS process. The detected polarization information is shown to be useful in classifying materials as well as detecting incoming light ray directions for use in autonomous agent navigations. Different algorithms used by the eyes of insects to detect motion were also studied and a model for collision detection has been proposed.
