Forward-looking: Researchers have developed a prototype device that converts infrared light into full-color images, offering a different approach to night vision that goes beyond the usual monochrome displays. The system, built by a team at the Beijing Institute of Technology, uses mercury telluride quantum dots paired with a dual-layer OLED. Instead of translating infrared into a single color based on brightness, the device maps different wavelengths and intensities into distinct visible colors.
That distinction is key. Traditional infrared imaging systems rely on detectors that capture a broad range of wavelengths but don't preserve much detail about them, so the output is typically rendered as brightness differences in a single color, often green. Effective as that is, it doesn't take advantage of how well the human eye can distinguish subtle color changes.
The new ...
