High Spatial and Time Resolution Characterization of Nanostructured Infrared Materials for Thermal Signature Management, Thermal Camouflage and Chemical
Abstract
The ability to control and detect the infrared response from a target surface using advanced optical structures is of great importance for a broad range of defense applications, such as thermal signature management, Lidar, heat-tracking systems, and chemical and biological sensing. Recently, nanostructured or nanophotonic materials have offered a promising platform for developing 2-D or 3-D complex infrared structures with tunable and ultrafast responses. In the past years, my DoD-sponsored research group has developed a variety of nanophotonic structures for controlling and detecting the infrared responses from materials, offering exciting opportunities for the DoD related applications in thermal signature management, thermal camouflage, and chemical sensing. Although the overall spectral response of the nanophotonic structures can be characterized by a Fourier Transform Infrared Spectrometer, it does not provide any spatial and temporal thermal emission information. In order to design and maximize the infrared performance of the nanophotonic structures, we require an infrared emission and temperature mapping system that enables high spatial and time resolution characterizations for real-time thermal emission or temperature measurements. Currently, no such infrared emission and temperature measurement system with both high spatial and time resolutions exists at Carnegie Mellon University and this has significantly impaired our ability to proceed in our efforts to design nanostructured infrared materials and improve their performance.
