Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...

This story follows the moment a scratch-built pinhole camera stopped being a rough experiment and started producing real, usable photographs. The stakes come from the fact that the first version still ...
