SBIR Phase I: A Miniaturized Sensor for Determining the Optical Properties of Aerosols

这个小型企业创新研究(SBIR)第一阶段项目将开发一种手掌大小的低成本仪器，用于测量空气中黑碳气溶胶颗粒的特征和分布。在现有分析仪的基础上，光学特性分析仪将在微型封装中使用气溶胶光吸收的光声检测。目前的仪器太大，不容易在高层大气中部署。这一拟议项目的成果是开发了一种低成本但坚固和准确的传感器，可部署在多个平台、有人和无人驾驶的飞机、气球、海洋浮标、塔楼和城市监测站。如果成功，一旦向国际社会提供这项新技术，这项活动的更广泛影响将源于知识的迅速传播。这一新仪器避开了目前在研究和监测应用中使用的技术的局限性。

This Small Business Innovation Research (SBIR) Phase I project will develop a palm-sized and low-cost instrument for measuring the characteristics and distribution of airborne black carbon aerosol particles. Based on an existing analyzer, the optical property analyzer will use photoacoustic detection of aerosol light absorption in a miniature package. Current instruments are too large to be deployed easily in the upper atmosphere. The outcome of this proposed project is the development of a low cost but robust and accurate sensor that can be deployed on multiple platforms, manned and unmanned aircraft, balloons, ocean buoys, towers and in urban monitoring stations. If successful the broader impact of this activity will stem from rapid diffusion of knowledge that will occur once this new technology is made available to the international community. This new instrument circumvents the limitations of the technology that is currently being used in both research and monitoring applications.
