Terahertz Frequency Continuous-Wave Spectroscopy and Imaging of Explosive Substances

Figure 6

Plot of Lorentzian fit algorithm performed on the composition 4 (C-4) absorption spectrum. Grey dashed lines represent individual Lorentz lineshape functions with their central peaks annotated on the plot. The red dashed line represents the superimposed resultant fit. The solid line is the original spectrum. The spectral peaks as computed by the Lorentz algorithm are 0.85, 1.02, and 1.38 THz.
