## Caption

Pinhole imaging is one of the earliest forms of #photography.

A traditional pinhole camera lets light pass through a tiny hole in a lightproof box, projecting an inverted image of the outside scene onto the opposite surface inside.

Inspired by pinhole imaging, researchers used laser light to form a tiny “optical pinhole” inside a nonlinear crystal, turning the infrared image into a visible image that a traditional silicon-based camera sensor can detect.

With this setup, the researchers captured clear, wide-depth images without using any lenses, even in very low light.
