A foveated wide angle lens for active vision

We present a novel design and implementation of a foveated wide angle lens. It is strongly motivated towards applications for active vision in complex and dynamic environments. The projection curve is designed so that it facilitates active vision algorithms for motion analysis, object identification, and precise fixation. The implementation achieves small size and light weight so that the lens can be swung at a high speed.
