Abstract
A covert information viewing system converts visible light to infrared wavelengths that can be transmitted for detection by an infrared-sensitive detector, such as night vision goggles, without detection by the human eye. The system includes a visible light information source emitting radiation as visible light, and a covert covering including an energy converting layer for absorbing the visible light emitted from the visible light information source and converting the visible light to infrared wavelengths, and a light blocking layer capable of absorbing unconverted visible light and transmitting infrared wavelengths. The covert covering is attached to the visible light information source and oriented to cover visible light emitted from the visible light information source, but it is also easily removed from the visible light information source.
