Mantis shrimp -aggressive, predatory sea crustaceans – have among the most sophisticated vision of all animals. A group of researchers, including Viktor Gruev, PhD, is recreating that vision to make specialized sensors and cameras that could bring more precision to biomedical imaging. Mantis shrimp eyes have extra sensors that allows them to see polarized light. Inspired by the mantis shrimp’s superior eyesight, researchers are building polarization cameras that could be used to help diagnose and remove cancerous tumors. At Washington University, Spencer Lake, PhD is using a polarization camera for studying ligaments. Lake is making strides toward improving ACL and PCL reconstruction surgeries.
