A phase feature extraction technique for terahertz reflection spectroscopy
Hua Zhong, Cunlin Zhang, Liangliang Zhang, Yuejin Zhao, and Xi-Cheng Zhang
We present a feature extraction technique for identification of explosive and biological materials using terahertz reflection time-domain spectroscopy (RTDS). The absorption signatures of the materials are extracted directly from the second-order derivative of the phase of the sample beam with respe ... [Appl. Phys. Lett. 92, 221106 (2008)] published Tue Jun 3, 2008.
