All-optical, near-infrared imaging via ultra-thin structured films
0
Near-Infrared (NIR) vision detectors and cameras play an essential role in today's high-tech tools for imaging, sensing and display technologies. Goggle- or binocular-based NIR cameras are particularly important for night vision, as well as medical and agriculture imaging. In conventional NIR cameras, the NIR light (700−2500 nm) is absorbed via a photocathode, leading to the discharge of electrons, which consequently strike an integrated flat screen, viewed by the eye or by an imaging sensor.
