Jumping spider eyes inspire future technology: giving nanorobots better optical capabilities

When a jumping spider intercepts a fly from a distance, its raid must be carried out with precision, foreign media reported. To do this, each eye of a spider has a multi-layered retina. As the image of one eye becomes clearer and the image of the other becomes more blurry, a deep focus appears, allowing the spider to immediately determine the exact distance required for a fatal jump.

The ability to jump spiders has inspired Researchers at Harvard University, who have developed a sophisticated new lens, or “metal lens”, for micro-robots and other micro-scientists.

It is understood that this lens can produce different blur slabs at the same time, unlike jumping spiders, metal lenses can separate light to form two different defocusimages, rather than using multiple layers of retina to capture multiple images at the same time. The data is then entered into an algorithm to obtain a complete image.

“Metal lensing is a game-changing technology because it enables more efficient, faster, less volume and less complexity to implement existing and new optical functions than existing lenses,” co-author Frederico Capasso said in a presentation at Harvard University. “

While deep sensors in mobile phones, cars and video game consoles can measure distances by using multiple cameras, the researchers hope the development of the new lens will allow the camera to combine with nanotechnology, micro-robots and smaller wearables.
