Abstract
A spectrometric system, including: a solid rocket fuel; an illuminating source including at least two wavelengths within a spectral range from 100 nm to 200,000 nm, a first wavelength or range of wavelengths having a distinguishably greater or lesser absorbance for the stabilizer than for components of the propellant, and a second wavelength or range of wavelengths having an absorbance for the stabilizer not distinguishably different than the absorbance for the components of the propellant, an illuminating fiber to illuminate a surface of a solid rocket fuel; a collecting fiber to collect back scattered, reflected or transmitted light being given off from the surface of the solid rocket fuel; and a spectrometer to determine the light intensities of the two wavelengths of the back scattered, reflected or transmitted light collected.
