Hmm, so if I understand the paper (which I might not), the lens is created by one laser beam, and then light from the sample causes a two photon effect in the lens area. Since two photon effects continue propagation, it’s in effect a pinhole which can be used for imaging. This seems like quite an elegant experiment.
Too bad you need to keep blasting the crystal with a laser to make this work
Is that a problem though? As long as the new camera is better than the old one, it should be fine.
I was hoping it was more of a process done to the crystal so it could make cheap and better heat cameras
Yeah well, passive components are nice, but occasionally you just need to spend some energy to keep the components doing its thing.
Okay, that’s very cool work.
