SBIR Phase I: Compact, Eyesafe LIDAR for Ozone Monitoring

*9761006 Carrig这个小型企业创新研究(SBIR)第一阶段项目使用先进的固态激光技术和激光雷达工程，实现了紧凑型、交钥匙、人眼安全的差分吸收激光雷达(DIAL)，适用于距离长达3公里的臭氧的距离分辨大气剖面。处于臭氧未达标状态的市政当局需要这样的系统，以便针对实际污染源。新的Dial系统基于一种频率捷变紫外线(UV)激光发射器，它比现有的UV激光源小得多，效率也更高。这将使移动遥控器变得更轻、更紧凑，而且可能比目前的紫外线刻度盘更便宜。此外，第一阶段将采用激光雷达收发技术，有效地应用于飞行合格的风力传感系统。这包括一个具有易于使用的图形用户界面的实时信号处理器。在第一阶段，将完成一个完整的交钥匙系统设计。在第二阶段，将建造一个原型装置。还将研究该激光雷达在大气中测量二氧化硫和颗粒物的适用性。初级市场是被宣布为臭氧未达标状态的地方和区域市政当局。该传感器可以进行改装，以测定二氧化硫的浓度。该仪器还可用于远距离对流层和平流层臭氧测量。***

*** 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. ***
