Researchers revive the pinhole camera for next-gen infrared imaging
Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a large range of distances and in low light, making it useful for situations that are challenging for traditional cameras.

Okay, that’s very cool work.

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.

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.
