Research:This Small Grant for Exploratory Research is being funded under NSF 02-2: "Next Generation Chemical and Biological Sensors and Sensing Systems." The objective of the research is to establish proof-of-concept of a novel way to monitor, detect, and characterize concealed biological and chemical agents that pose threats to people, buildings, mass transportation, urban environments, mail/packages, etc. The method to be studied is non-invasive, and allows for real-time, wide-area/field-of-view surveillance. The technical approach is to detect these agents via spatial interferometric imaging of their characteristic transmission or reflectivity wavelength spectrum in the Terahertz (THz) electro-magnetic radiation range (0.1-3 THz). Neural network analyses of the THz spectra and images will provide the specificity of agent detection and reduce the frequency of false alarms.Impact:The research is to promote homeland security - its impact is thus timely and important. In addition, the institution has a primarily minority student population.

研究：这笔用于探索性研究的小额赠款由 NSF 02-2 资助：“下一代化学和生物传感器及传感系统”。 该研究的目的是建立一种新方法的概念验证，以监测、检测和表征对人类、建筑物、公共交通、城市环境、邮件/包裹等构成威胁的隐藏生物和化学制剂。要研究的方法是非侵入性的，并且允许实时、广域/视场监视。 技术方法是通过太赫兹（THz）电磁辐射范围（0.1-3 THz）内特征透射或反射率波长谱的空间干涉成像来检测这些物质。 太赫兹光谱和图像的神经网络分析将提供代理检测的特异性并减少误报的频率。影响：该研究旨在促进国土安全 - 因此其影响是及时且重要的。 此外，该机构的学生主要是少数族裔。
