The terahertz absorption spectrum of the five aging explosive samples (PETN, RDX, HMX, LLM-105 and TATB) was measured and calculated by Terahertz time-domain spectroscopy system (THz-TDS) and air-biased coherent detection system (ZAP-ABCD), respectively. In this paper, compared with the unaging explosive, each aging explosive sample’s terahertz time-domain spectra were obtained and the terahertz absorption spectra were calculated by using Fourier transform and Lambert’s law. The results show that there are several terahertz absorption peaks which were called “fingerprint spectra” for different aging explosive samples in the range of 0.3–6.0 THz spectrum. Meanwhile, the results also show that the locations of the characteristic absorption peaks are not the same. Moreover, the unaging and aging explosive samples have obviously different terahertz absorption spectra.

Terahertz wave lies between far-infrared and microwave in electromagnetic spectrum with frequency form 0.1 THz to10 THz. Terahertz is believed to be the master technology of electronics and information science, and to be the bridge between micro electronics and macro wavelength. THz has formed a worldwide research climax. This paper introduces the main characters of Terahertz wave, Terahertz time-domain spectroscopy technology and its application researches, especially detailed the researches in pesticide spectra.
