Ancient 4th-century pinhole concept reimagined in lens-free infrared camera design
A laser-driven “optical pinhole” unlocks distortion-free mid-infrared imaging for night vision and environmental monitoring.
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 ...
