　　You who are excited about the colorful colors in the world in your eyes, it may be difficult to imagine what a world with the entire spectrum from near ultraviolet to infrared and 12 primary colors in the eyes of the little mantis shrimp under the water would look like. Recently, a new study has once again consolidated the throne of "the best eyes in the world" of mantis shrimps-they can also see polarized light.

　　Researchers from the University of Queensland in Australia found that the compound eyes of the mantis shrimp can well detect polarized light that is imperceptible to the human eye. It has become an excellent template for scientists to develop new cameras. The imaging equipment developed based on this will be used in the future. Detect cancer and observe brain activity.

　　Justin Marshall of the University of Queensland Brain Research Institute said: “The'color' that people see is made up of tones and shadows, and they are distinguished by the difference between objects. For example, people see red apples hanging on a green tree (among them The shades, shades, and shapes of the two are different). Polarized light is not far away from us. Common polarized sunglasses are a good example. They can reflect polarized light and reduce the glare from water or wet roads. Irritating to human eyes."

　　Medical research has found that cancerous tissue reflects polarized light that is different from the surrounding healthy tissues, and the compound eyes of mantis shrimp can very clearly capture this polarized light that is invisible to the human eye, and can use polarized light to detect and distinguish objects. This discovery undoubtedly makes it possible for researchers to detect cancer tissues through visual images.

　　Researchers from the University of Queensland and the United Kingdom and the United States have jointly developed a new camera that mimics the eyes of a shrimp, which can process the captured images and convert the previously invisible information into human-visible color signals. This kind of image can feed back the cancerous area or monitor the activity of nerve cells in real time. In the future, it can effectively improve the efficiency of cancer detection, reduce the tedious biopsy steps, and can also be used to guide surgical procedures. This technology may also promote the upgrade of smart phone cameras in the future, helping people quickly check their health anytime, anywhere, and carry out targeted treatment early.

　　But wanting to "see" the light emitted by neurons and identify cancer tissues with their own eyes is still beyond the current technical level of people, and researchers need to further study. However, people can now learn from the ingenious eye structure that the mantis shrimp has evolved over millions of years. After research, analysis and re-architecting, the best solution can be found concisely and efficiently, greatly shortening the time for scientists to design from scratch.

　　Currently, the University of Queensland Brain Research Institute has also joined forces with the University of Washington School of Medicine, the University of Maryland at Baltimore, and the University of Bristol to jointly develop this technology. This time the joint research team has assembled experts in optic nerve technology, physics and optoelectronic engineering technology. This kind of interdisciplinary cooperation is believed to accelerate the development of new technologies.
