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 ...

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 ...

Pinhole (or lens-less) photography is one of the oldest forms of photography there is. With endless options of high-tech cameras and far less temperamental gadgets, not many opt for such a primitive ...
