Covert information viewing system and method of covert information processing

A method of covert information processing comprising:

• providing a visible light information source configured to emit radiation as visible light, a covert covering comprising an energy conversion layer and a light blocking layer, and an infrared emissions detector;
• removably attaching the covert covering proximate to the visible light information source to cover visible light emitted from the information source;
• absorbing and converting visible light emitted from the visible light information source to infrared emission information as it passes through the covert covering, wherein the light blocking layer is capable of absorbing any residual visible light emitted by the visible light information source that is unconverted by the covert covering;
• and
• processing the infrared emission information emitted from the covert covering with the infrared emission detector.

A system for covertly viewing an environment comprising:

• a visible light source that is configured to emit radiation as visible light;
• and
• a covert covering comprising:
• an energy converting layer capable of absorbing at least a portion of the visible light emitted from the visible light source and converting the absorbed visible light to infrared radiation;
• and
• a light blocking layer capable of absorbing any residual visible light emitted by the visible light source that is unconverted by the energy converting layer and transmitting infrared wavelengths;
• wherein the covert covering is removably attached to the visible light source and oriented in position to cover visible light emitted from the visible light emitting surface source;
• and
• wherein the infrared information from the environment radiation can be viewed using an infrared detector.

A method of covertly viewing an environment comprising:

• emitting visible light from a visible light source;
• converting the visible light to infrared radiation using a covert covering removably attached proximate to the light source to cover visible light emitted from the light source, the covert covering comprising an energy conversion layer and a light blocking layer, wherein the light blocking layer is capable of absorbing any residual visible light emitted by the visible light source that is not converted to infrared radiation;
• directing the emitted infrared radiation to an environment to be viewed;
• and
• processing infrared emission information collected from the environment with an infrared emission detector.

A method of viewing covert information comprising:

• emitting visible light from a visible light information source;
• absorbing and converting visible light emitted from the visible light information source to infrared emission as it passes through a visible light blocking film, wherein the visible light blocking film is capable of absorbing any residual visible light emitted by the visible light information source that is not converted to infrared emission;
• and
• imparting information into said infrared wavelengths emission by reflecting the infrared emission from an information pattern;
• transmitting said infrared wavelengths emission through the visible light blocking film;
• and
• processing infrared emission information collected from the visible light blocking film with an infrared emission detector.
