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.
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.
