A survey of insect eye inspired visual sensors

Recent progress on computer technologies is focused on mobility and size reduction rather than functionality. That provided us researchers and commercial manufacturers with low-cost, compact and high-capability electronic hardware. Visual sensors are no exception. Hereby in the light of recent technological advance it is possible to organize sensors with a two dimension array hierarchy and build very-capable systems which are not enormous. These systems can be used and is being used in variety of needs like surveillance, virtual environment applications and robotic vision. Nature is a step ahead of us in this subject.
