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 ...
Pinhole cameras are not new; they have been around since the beginning of photography. The concept was around long before that. The ancient Chinese and Greeks understood the notion of a pinhole device ...
OK, you want to view the Sun or an eclipse, but you don’t have an approved solar filter for your telescope. Maybe you don’t even have a telescope. No problem! I’ll bet you have a cardboard box. That ...
