Programmable Infrared Surface Emissivity (334)
Problem: Need for durable high-emissivity surfaces and infrared (IR) tagging and identification technology
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Circuits and Devices
PNNL Solution:
- Cover surface with array of closely-spaced "micropits" that act as perfect "black-body" thermal emitters
- The aperture of each pit is a thermal "pixel" in the array
- Controllable micro-mechanical covers open or close each aperture
- Results in emissivity control and/or IR camouflage/identification capability
Capabilities Employed to Meet Client Needs: Surface physics, micro-electromechanical structures and systems, material preparation; thermal and optical systems analysis and integration; testing and analysis.
