In various space tasks such as space rendezvous-docking and on-orbit maintenance, the measurement of the relative posture and position of non-cooperative spacecraft is a key component. However, the ...

Modern camera lenses are really good. In fact, the engineers have done pretty much everything they can to engineer characteristics like distortion out of the glass. But if you’re still worried about ...

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 ...
