SBIR Phase I: An Improved Open-Path FTIR Spectrometer for Remote Monitoring of Atmospheric Gases

这个SBIR第一阶段项目将开发一种改进的开路FTIR光谱仪，用于远距离监测大气气体。这将通过开发一种高亮度红外源来实现，该红外源通过半导体激光器加热到2000K。该项目的更广泛/商业影响将是提供一种解决方案，该解决方案将减少当前OP-FTIR技术中发现的几个限制，即提高的资本成本、尺寸、功率要求和/或灵敏度。这种方法将扩大OP-FTIR用于EPA和ASTM方法监测大气气体的范围，这些好处可能有助于这项技术的实施，并使其适用于其他应用，如闭路FTIR系统。

This SBIR Phase I project will develop an improved Open-Path FTIR Spectrometer for monitoring of atmospheric gases over extended distances. This will be achieved by developing a high-brightness infrared source that is heated to 2000 K by means of a diode laser. This will enable the instrument to be less bulky and expensive, and will have improved monitoring range over current systems.The broader/commercial impact of the project will be to provide a solution that will reduce several limitations that are found in current OP-FTIR technologies, namely, elevated capital costs, size, power requirement, and/or sensitivity. The approach will broaden the use OP-FTIR for monitoring atmospheric gases by EPA and ASTM methods, and these benefits may help implement this technology and make it applicable for other applications such as closed path FTIR systems.
