Do you know how you see those cheap telescopes at the department store? The box has beautiful pictures that probably came from the Hubble. What you will see is somewhat different. You have to ...

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 ...

A team of researchers in China has developed a lens-free imaging system that produces sharp mid-infrared images even in low light and across long distances. The breakthrough promises improvements for ...
