SBIR Phase I: Compact, Eyesafe LIDAR for Ozone Monitoring

这个小型企业创新研究（SBIR）一期项目采用先进的固态激光技术和激光雷达工程技术，开发出一种紧凑、完整、安全的差分吸收激光雷达（DIAL），适用于距离分辨大气臭氧分析，探测距离可达3公里。在处于臭氧不达标状态的城市需要这种系统，以便针对实际污染源。新的DIAL系统基于频率变捷紫外（UV）激光发射机，该发射机比现有的紫外激光源更小，效率更高。这将使移动远程传感器更轻，更紧凑，并且可能比目前的UV DIALS更便宜。此外，第一阶段将把激光雷达收发器技术有效地应用于飞行合格的风传感系统。这包括一个实时信号处理器，具有易于使用的图形用户界面。在第一阶段，将完成完整的交钥匙系统设计。在第二阶段，将建造一个原型设备。该激光雷达在大气二氧化硫和颗粒物测量中的适用性也将被研究。主要市场是宣布处于臭氧不达标状态的地方和区域市政当局。该传感器可以修改为二氧化硫的分析。该仪器还可用于对流层和平流层臭氧的远程测量。＊＊＊

*** 9761006 Carrig This Small Business Innovation Research (SBIR) Phase I project uses advanced solid-state laser technology and lidar engineering for a compact, turn-key, eyesafe differential absorption lidar (DIAL), suitable for range-resolved atmospheric profiling of ozone to distances of up to three kilometers. Such systems are needed in municipalities in ozone nonattainment status in order to target actual pollution sources. The new DIAL system is based on a frequency-agile ultraviolet (UV) laser transmitter that is substantially smaller and more efficient than existing UV laser sources. This will permit mobile remote sensors that are lighter, more compact, and potentially less expensive than current UV DIALS. Further, Phase I will incorporate lidar transceiver technology effective in flight-qualified wind-sensing systems. This includes a real-time signal processor with an easy-to-use graphical user interface. In Phase I a complete turn-key system design will be completed. In Phase II a prototype device would be built. The applicability of this lidar for atmospheric measurements of sulfur dioxide and particulate matter will also be investigated. The primary market is local and regional municipalities declared to be in ozone nonattainment status. The sensor can be modified for profiling of sulfur dioxide. The instrument will also be scaleable for long-range tropospheric and stratospheric ozone measurements. ***
