Miniaturized low-power artificial compound eyes in a small form factor and a low payload can be a promising approach to provide wide-field information for micro-air-vehicle (MAV) applications. Recently, research efforts have been made to realize bio-inspired artificial compound eyes to mimic the wide field of view (FoV) of insect visual organs by implementing photoreceptors to independently face different angles [1-2]. However, these approaches have drawbacks. They use complicated fabrication processes to form a hemispherical lens configuration and secure an independent optical path to each photoreceptor. We take a simple and practical approach to realize wide-field optic flow sensing in a pseudo-hemispherical configuration by mounting a number of 2D array optic flow sensors on a flexible PCB module as shown in Figure 7.2.1. In this scheme, the 2D optic flow sensor should meet the requirements of MAV applications:
