SGER: Chemical-Agent Identifier Based on THz Absorption Spectroscopy

利哈伊大学的丁玉杰教授正在开发太赫兹频段分子光谱的新方法。我们的想法是制造一种坚固、便携和可靠的紧凑型化学识别器，用于有毒气体(例如化学作战剂)的存在和/或浓度。该项目的目标是用改进的太赫兹探测器类型、改进的实验方法和改进的太赫兹源进行概念验证实验。一名研究生将参与这个太赫兹光谱学项目。该奖项由美国国家科学基金会和情报团体共同资助。数学和物理科学局的反恐方法方案支持基础研究和劳动力发展方面的新概念，有可能对国家安全作出贡献。

ABSTRACTProfessor Yujie J. Ding of Lehigh University is developing new methods for molecular spectroscopy in the THz frequency region. The idea is to make a rugged, portable and reliable compact chemical identifier for the presence and/or concentration of toxic gases (e.g. Chemical Warfare Agents). The goal of this project is to perform proof-of-concept experiments with improved types of THz detectors, improved experimental methodologies, and improved THz sources. One graduate student will be involved in this THz spectroscopy project.This award is supported jointly by the NSF and the Intelligence Community. The Approaches to Combat Terrorism Program in the Directorate for Mathematics and Physical Sciences supports new concepts in basic research and workforce development with the potential to contribute to national security.
