You don’t always need a lens to see a picture, you can use a pinhole camera instead. A pinhole camera uses a small hole that allows light to pass through to allow your eye to see an image. This was ...

Pinhole photography works by allowing light to pass through a small hole in the body cap. The purpose of this hole is to restrict the amount of light reaching the sensor, creating an almost infinite ...

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 ...
