0339310这个小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。该新颖的全固态的基于激光的系统可以在许多实施例中被配置成用于步行通过、行李和货物检查入口，并且可以潜在地被制造成用于扫雷应用的便携式版本。所提出的传感器将结合联合收割机一种新的激光技术与一种新的检测方法，以超过目前采用的离子迁移率质谱为基础的系统的检测极限的数量级。该传感器将能够以无与伦比的灵敏度在真实的时间内快速检测和区分不同炸药的超痕量水平。该传感器将能够在不到10秒的时间内检测出TNT、RDX和PETN等浓度为万亿分之一的普通爆炸物，并具有高度的化学特异性。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。该仪器还可用于化学战剂和潜在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。

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.
