Mantis shrimp have a very complex visual system that allows them to detect light in a logarithmic fashion, giving them the ability to detect a large range of light including polarized light. A new camera, costing less than $10 to manufacture, inspired by this system mimics this logarithmic response by using a forward bias mode technique instead of a reverse bias mode, creating a dynamic range 10,000 times higher than current commercial cameras. Researchers also included nano materials that act as polarization filters, allowing the camera to detect polarized light. The resulting more sensitive camera has been tested in self driving cars to lessen the possibility of weather induced accidents. The higher dynamic range is better able to detect objects in suboptimal conditions (fog, rain, etc) that can potentially lessen the amount of vehicle collisions with road hazards.
