Terahertz Technology

The detection of landmines has become a hard task to deal with because of the diversity of landmines and the complexity of minefield. The development of terahertz technologies has provided a feasible way to detect the buried landmines. Landmines’ shell is usually made of ceramics, plastics, even wood and so on, which terahertz wave could penetrate them easily. The explosives are the major part of landmines. Many types of explosives have the characteristic spectrum in terahertz range, so it would be an effective method to detect landmines by measuring the spectrum of explosives with terahertz time-domain spectroscopy.

Time Domain Spectroscopy

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.

The signal-to-noise ratio obtained from terahertz time-domain spectroscopy is significantly affected by the low available power of terahertz waves. We constructed a terahertz-wave source with emission power enhanced by a magnetic field. The emitter is composed of an InAs wafer and two neodymium magnets. The emitter was irradiated by femtosecond laser pulses. The data quality of terahertz spectroscopic measurements was evaluated, and reduction of error in the data obtained due to the terahertz power enhancement was observed.
