Scientists achieve full-color night vision without thermal imaging
Source: Ars Technica
Researchers have converted infrared photons into visible light wavelengths in real time, solving a longstanding engineering problem that constrained night vision to monochrome. Military and law enforcement have been forced to choose between thermal imaging, which shows heat signatures but loses visual detail, and amplified night vision, which preserves some color but requires ambient light. A full-color night vision system would combine thermal data with color information, improving tactical operations, surveillance, and search-and-rescue work by leveraging the human eye's ability to recognize objects by color.
