Infrared Reflectance of Solids


EMSL Project ID
37295

Abstract

Imaging technologies have been under development for more than 30 years but have only recently been proposed for comprehensive applications. The earliest public sensor and exploitation development was in the reflective domain (~.4 - 2.5 micrometer, VIS/NIR/SWIR) and was aimed primarily at the identification of solid materials and water quality. This technology is well developed for many applications: both hardware and software have been commercialized, and it has been integrated to some degree. More recently, there has been development of hyperspectral technology in the long wave thermal infrared (LWIR, ~7.5 - 14 micrometer) as well as some development in the midwave infrared (MIR, ~3 - 5 micrometer). The thermal IR exploitation technologies have been developed primarily for the detection and identification of gaseous effluents from facilities. Spectral signatures for solid materials and for gasses are fundamentally different and exploitation of MWIR and LWIR for detecting and identifying solid materials of interest to nonproliferation detection has lagged. The major objective of the proposed work is to provide enabling data and understanding of one of the major hurdles: knowledge of the spectral emissivity of real surfaces that are observed by remote sensing systems. Specifically, we will be developing vetted protocols fro the delivery of infrared reflectance data for remote sensing.
