"Avian eye-inspired perovskite artificial vision system for foveated and multispectral imaging".

The paper is paywalled, but from the abstract what I'm able to figure out is these researchers have developed an, essentially, digital camera, except unlike a regular digital camera which produces pictures with a uniform density of pixels everywhere, this camera has a ton of extra pixels in the center of the image, giving it a "fovea" like birds of prey. Also, like bird eyes, this "foveated" digital camera can see ultraviolet light, in addition to regular visible light.

If any of you can get around the paywall it would be interesting to find out if the reason it's made with perovskites is to provide this additional ultraviolet detection. The say it's construction is a "vertically stacked perovskite photodetector". This may mean it's not a charge-coupled device (CCD) like regular digital cameras.

This is obviously a research product so no word yet on commercialization, but it seems obvious to me that this has immediate application in military drones.
