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 ...
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 ...
