FIG. 1.

(a) Fourier transform amplitude of the measured terahertz waveform after transmitting through a PE pellet (curve 1) and a RDX pellet (curve 2). (b) Absorption (power) spectrum of RDX pellet measured using a terahertz pulsed spectrometer (curve 1) and a FTIR spectrometer (curve 2).

FIG. 2.

(Color online) Schematic diagram of the sample (a), and its terahertz time-domain image (peak amplitude) (b). False-color terahertz chemical maps showing the spatial distributions of lactose (c), sucrose (d), and RDX (e).

Image of FIG. 3.
FIG. 3.

(a) Fourier transform amplitude of the measured terahertzwaveforms after reflecting from a PE pellet (curve 1) and a piece of RDX explosive (curve 2). The inset show the terahertz wave form measured for RDX explosive. (b) The first derivative absorption spectrum of RDX explosive obtained from a reflection measurement (curve 1) and a transmission measurement (curve 2).
