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 ...
BERLIN (Reuters) - An American artist is attempting to create a photographic portrait of Berlin that will capture the city over 100 years in a single shot from pinhole cameras in 100 secret locations.
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 ...
