This article describes how nano metalenses work and what they can be used for.
Spoiler alert: they can't be used to replace your smartphone's camera lenses yet, but can be used for IR distance sensors used on drones and soon, polarization sensors that will be able to tell materials apart and even detect cracks in concrete.
- nomel 3y ago> polarization sensors that will be able to tell materials apart Video of Gavin Smith explaining polarization with a neat mechanical/visual demonstration: https://youtu.be/9SAzxlF57mc?feature=shared&t=128 https://youtu.be/9SAzxlF57mc?feature=shared&t=128 Not sure if he ever made the camera.
- hbarka 3y agoI wonder if this has applications for sensing in self-driving cars.
- codetrotter 3y agoAI-equipped cars with a real sense of feeling in their tires. It’ll be like the sensation of touch for them. Everything they run over, they will feel. Make them learn that animals feel gross to touch. Make them feel remorse for running over a human. Boom! Self-driving safety solved!
- psd1 3y agoThis opens the door to kinky AI
- throwup238 3y agoYeah that’s exactly what we need. An AI that calls us “daddy” That can’t possibly go wrong. Nope.

- empyrrhicist 3y ago> feeling in their tires. Ignoring the rest... I feel like this would be much easier to accomplish with acoustic sensors and wheel/suspension telemetry, given that an attentive human driver can sort of "feel" the road surface already.
- TeMPOraL 3y agoOne step closer to a tricorder.
