Smartphone Cameras Might Soon Capture Polarization Data

Imagine a camera that's mounted on your car being able to identify black ice on the road, giving you a heads-up before you drive over it. Or a cell phone camera that can tell whether a lesion on your skin is possibly cancerous. Or the ability for Face ID to work even when you have a face mask on. These are all possibilities Metalenz is touting with its new PolarEyes polarization technology. Last year, the company unveiled a flat-lens system called optical metasurfaces for mobile devices that took up less space while purportedly producing similar- if not better-quality images than a traditional smartphone camera.
