SBIR Phase I: Ultrasensitive, Real-Time Explosives Sensor

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。这种新型的全固态激光系统可以配置在许多实施例中，用于穿越、行李和货物筛选门户，并且可能以便携式版本制造，用于扫雷应用。提出的传感器将结合一种新的激光技术和一种新的检测方法，以超过目前采用的基于离子迁移率质谱系统的检测极限数量级。该传感器将能够以无与伦比的灵敏度实时快速探测和区分不同爆炸物的超痕量水平。该传感器可以在10秒内检测出TNT、RDX、PETN等浓度为万亿分之一的普通爆炸物，具有很高的化学特异性。这种传感器系统的商业市场是巨大的，需求是迫切的。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。同样的仪器也可用于化学战剂和潜在的生物战剂的痕量探测。除了安全应用之外，相同的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.
