This microlens camera can ‘see’ like an eagle

When you want to talk about sharp eye sight, talk about the "eagle eye''. No matter the distance of an eagle above the ground, there is virtually nothing it can't see clearly. Considering that characteristic, a new tiny camera lens that works the same way has been made.
Having spy gadgets in mind, scientists started working on the microlens a few years ago, but this new version features improvements to the lens’s field of view and focusing ability. This latest version immersed in a plastic casing with a 3D printer acts like an eagle eye. The camera uses four lenses instead of one, each set at different focal lengths and mounted on an image-reading microchip that compiles data from all four lenses into a single image. 

These microlenses work by mimicking something called foveated vision, which allows many predators to see a wide field of view at low resolution and focus on a single object at high resolution at the same time. Eagles have really deep foveae with lots of cones, which is why “eagle eye” is used to describe great vision.

The chip is not yet ready for service, it has low resolution and it takes several hours to 3D-print each individual lens. When these are resolved, it could be used in so many areas like the Health sector during surgery, and also used to spy on culprits as supersmall surveillance drones.
