Researchers develop full-color night vision goggles using a dual-emitter OLED upconverter device
Researchers at the Beijing Institute of Technology have developed night vision goggles that provide full-color images by using a dual-emitter OLED upconverter. The device uses quantum dot photodetectors to translate infrared light into specific colors based on intensity.
Why it matters
This innovation represents a significant leap in optical technology, potentially improving situational awareness for military and civilian night-vision applications.
Researchers from the Beijing Institute of Technology (BIT) have developed an infrared-to-visible upconversion device (night goggles) that stacks a mercury telluride (HgTe) colloidal quantum dot photodetector directly underneath a dual-emissive-layer OLED. Unlike previous upconverters, which output a single color and encode the infrared signal only as brightness, this device changes both its emitted color and its luminance depending on the wavelength and intensity of the incoming infrared light - effectively giving the wearer full-color infrared vision.
