Insect-inspired visual sensors

Obviously we know that insects, such as ants, are expert visual navigators but we have a limited understanding of how (if at all) the sensory physiology of ants is tuned to navigation. One approach to that question is to investigate how differently tuned sensors would perform at a navigational task, such as identifying stable environmental features. Many ants have UV and green photoreceptors which led to the suggestion that a UV-green contrast might be a good way to identify environmental features in the world. Here, Differt and Möller show that actually using the UV channel alone can be very useful for navigation, when the UV signal is simply thresholded useful a locally adaptive threshold. This is an interesting approach to thinking about sensor physiology, but also useful for designing sensors for navigating agents.
