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 use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...
