Active Mode Remote Infrared Spectroscopy Detection of TNT and PETN on Aluminum Substrates
Figure 2
Signal-to-noise ratio (principal y-axis) at various distances for active mode RIRS measurements of TNT. IR beam spot size (secondary y-axis) versus range. Noise levels (as standard deviation) were measured at 830–870 cm−1 and peak heights were measured for TNT signal at 790 cm−1.
