In this research, a remotely located, high-speed, infrared (IR) camera is used to obtain detailed measurements of the passive radiation from an object in an energetic environment. This radiation information is used to determine both the emissivity and the temperature of the surface of an object. However, before the temperature or emissivity was determined, the functional form of the emissivity was assumed to be an Mth degree polynomial with respect to wavelength dependence. Using a commercial Fourier transform spectrometer, this functional form was verified to accuracy's on the order of 0.1%, to be a polynomial of the second degree. With the advent of large (greater than 128 X 128 pixels), high-speed, IR detector arrays, it has now become possible to realize IR imaging spectrometers that have very high spatial resolution. The IR spectrometer system developed in this research utilized a large detector array to allow multiple spectral images to be formed simultaneously on the image plane, with the information from each spectral image being concurrently collected. In conjunction with the correct emissivity model, this imaging IR spectrometer can determine the temperature of the surface of an object within an energetic environment to within +/- 5 degrees Celsius. These experimentally verified temperature/emissivity maps can then be integrated into the newly developed computer models. This additional information will result in more accurate computer codes for modeling the energetic environment. In turn, this will allow the weapon designer to optimize weapon performance with respect to different materials, geometries and kinetics.
