"A novel optics system that mimics the structure of a lobster’s eyes would enable a conceptual Explorer-class mission to precisely locate, characterize, and alert other observatories to the source of gravitational waves, which are caused by some of the most powerful events in the universe. [...] the WFI, is equipped with the novel lobster-eye optics, which mimic the structure of the crustacean’s eyes. Lobster eyes are made up of long, narrow cells that each reflect a tiny amount of light from a given direction. This allows the light from a wide viewing area to be focused into a single image."
