This Small Business Innovation Research (SBIR) Phase II research project seeks to develop a new, ultrasensitive laser based explosives detection system (EDS). The system will be capable of rapidly detecting and discriminating among common explosives materials in a timescale commensurate with that of existing passenger screening systems that are presently used in airports. The proposed EDS technology is based on a combination of a new, rapidly and widely tunable laser system with a novel optical cavity enhanced absorption method. The research effort comprises constructing and testing a bench top version of the system that is suitably configured for use in the middle infrared, where explosives can be detected via their characteristic spectral signatures. If successful, the instrument will be capable of significantly exceeding the sensitivity level of existing commercial EDS sensors, as well as potentially providing an orthogonal sensor platform.The sensor will be suitable for passenger, baggage, and cargo screening applications, and will be engineered specifically for integration as a plug-in replacement or parallel technology to existing screening systems. In addition to advancing laser technology, the project has the potential to benefit society by assuring safer transportation to the general public. The ability to rapidly scan the middle infrared spectral region with high absorption sensitivity will enable the rapid detection of numerous trace chemical species including toxic industrial chemicals, chemical warfare agents, and industrial pollutants.

这项小型企业创新研究（SBIR）II期研究项目旨在开发一种新的，超敏感的激光炸药检测系统（EDS）。该系统将能够在与目前在机场目前使用的现有乘客筛查系统相称的时间表中快速检测和区分普通炸药材料。拟议的EDS技术基于一种新的，快速且可调的激光系统与新型光腔增强吸收方法的组合。研究工作包括构建和测试系统的基准版本，该系统适当配置在中间红外，可以通过其特征性光谱特征检测炸药。如果成功的话，该仪器将能够显着超过现有商业EDS传感器的灵敏度水平，并有可能提供正交传感器平台。该传感器将适用于乘客，行李和货物筛查应用程序，并将专门设计为用于插入式替换或并行技术，用于现有筛选系统。除了推进激光技术外，该项目还可以通过确保向公众更安全的运输来使社会受益。快速扫描具有高吸收敏感性的中间红外光谱区域的能力将能够快速检测许多微量的化学物种，包括有毒工业化学物质，化学战剂和工业污染物。
