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 ...

Claire Gillo shares her top tips for re-creating a pinhole camera and how to develop your own film. A pinhole camera is simply a box or container that uses a literal pinhole for an aperture. Light ...

Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...
