Abstract
An infrared (IR) scene projector device includes a light emitter and a thermal emitter. The light emitter is configured to selectably provide visible light. The thermal emitter includes a vertically aligned carbon nanotube (VACN) array. The VACN array includes a plurality of carbon nanotubes disposed proximate to a thermally conductive substrate, such that a longitudinal axis of the carbon nanotubes extends substantially perpendicular to a surface of the substrate. The thermal emitter absorbs the visible light from the light emitter and converts the visible light from the light emitter into IR radiation.

An infrared (IR) scene projector device comprising:
- a light emitter configured to selectably provide visible light;
- and
- a thermal emitter comprising a vertically aligned carbon nanotube (VACN) array, the VACN array comprising a plurality of carbon nanotubes disposed proximate to a thermally conductive substrate such that a longitudinal axis of the carbon nanotubes extends substantially perpendicular to a surface of the substrate, the thermal emitter absorbing the visible light from the light emitter and converting the visible light from the light emitter into IR radiation.
A thermal emission array comprising:
- a thermally conductive substrate;
- and
- a plurality of vertically aligned carbon nanotubes (VACN), the carbon nanotubes being disposed proximate to the thermally conductive substrate such that a longitudinal axis of the carbon nanotubes extends substantially perpendicular to a surface of the substrate,
- wherein the carbon nanotubes convert visible light directed thereon into IR radiation, the IR radiation being emitted by thermal emission array based on selective provision of the visible light to the VACN.
