这个小型企业创新研究第一阶段项目旨在开发一种超灵敏、实时、基于激光的爆炸物传感器。这种新颖的、全固态、基于激光的系统可以在许多实施例中配置，用于步行、行李和货物检查门户，并可能被制造为便携式版本，用于扫雷应用。建议的传感器将结合新的激光技术和新的检测方法，以数量级超过目前使用的基于离子迁移率质谱仪的系统的检测极限。所提出的传感器将能够以无与伦比的灵敏度实时快速检测和区分不同炸药的超微量。该传感器将能够在10秒内以万分之几的浓度水平检测出TNT、RDX和PETN等常见爆炸物，并具有很高的化学特异性。这种传感器系统的商业市场巨大，需求迫切。拟议的仪器将能够以无与伦比的灵敏度和选择性实时探测爆炸物。同样的仪器也可以用于化学战和潜在的生物战剂的痕量检测。除了安全应用外，该传感器还可用于工业过程控制、环境监测和天然气传感等应用。

0339310This Small Business Innovation Research Phase I project seeks to develop an ultrasensitive, real-time, laser-based explosives sensor. The novel, all solid state, laser-based system can be configured in numerous embodiments for use in walk-through, baggage, and cargo screening portals and can potentially be manufactured in man-portable versions for mine sweeping applications. The proposed sensorwill combine a new laser technology with a new detection method to exceed the detection limits of presently employed ion mobility mass spectrometry based systems by orders of magnitude. The proposed sensor will be capable of rapidly detecting and discriminating among ultratrace levels of different explosives in real time with unparalleled sensitivity. The sensor will be capable of detecting common explosives such as TNT, RDX,and PETN at parts-per-trillion concentration level with high chemical specificity in less than 10 seconds.The commercial markets for such a sensor system are enormous and the need immediate. The proposed instrument will enable explosives to be detected in real-time with unparalelled sensitivity and selectivity. The same instrument can also be used for the trace detection of chemical warfare and potentially biological warfare agents. In addition to security applications, the same sensor can be used for applications in industrial process control, environmental monitoring, and natural gas sensing.
