Researchers devise a full-color night vision goggle
Researchers at the Beijing Institute of Technology have created a night‑vision goggle that renders infrared light as full‑color images. The device combines mercury telluride colloidal quantum dots with a dual‑layer OLED to convert infrared wavelengths into distinct visible hues. This approach aims to utilize human hue sensitivity, offering a more detailed perception than traditional brightness‑only infrared displays.
- ▪The new goggle translates infrared wavelengths into separate parts of the visible spectrum rather than representing them solely as brightness variations.
- ▪Mercury telluride quantum dots, about 4 nm in size, provide discrete energy levels that allow the device to differentiate infrared wavelengths.
- ▪A dual‑layer OLED converts the charge carriers generated by the quantum dots into ordinary‑looking, full‑color images.
- ▪Traditional infrared devices typically display a single greenish hue, limiting the eye’s ability to discern subtle differences.
- ▪The prototype was tested with infrared wavelengths up to approximately 2 micrometers, demonstrating the concept’s feasibility.

Infravision Researchers devise a full-color night vision goggle Wavelength and intensity in the infrared are translated into colors in the visible.

But we’ve been able to make devices that give us a visual representation of what’s happening in the infrared.
