*** 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. ***

*** 9761006 Carrig 这个小型企业创新研究 (SBIR) 第一阶段项目采用先进的固态激光技术和激光雷达工程，打造紧凑、交钥匙、人眼安全的差分吸收激光雷达 (DIAL)，适用于范围分辨大气剖面臭氧的传播距离可达三公里。 处于臭氧未达标状态的城市需要此类系统，以便针对实际污染源。 新的 DIAL 系统基于频率捷变的紫外线 (UV) 激光发射器，该发射器比现有的紫外线激光源更小、更高效。 这将使移动远程传感器变得更轻、更紧凑，并且可能比当前的 UV DIALS 更便宜。 此外，第一阶段将采用激光雷达收发器技术，该技术可有效用于符合飞行资格的风感测系统。 其中包括具有易于使用的图形用户界面的实时信号处理器。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。 还将研究该激光雷达对二氧化硫和颗粒物大气测量的适用性。 主要市场是被宣布处于臭氧未达标状态的地方和地区城市。 该传感器可以进行修改以分析二氧化硫。 该仪器还可扩展用于远程对流层和平流层臭氧测量。 ***
