The broader impact/commercial potential of this I-Corps project is to reduce or eliminate damage/loss of property and protect public health and safety by introducing infrared and eye-safe laser radar (lidar) technology for high sensitivity remote plume characterization. The technology has the potential to meet a diverse range of customer sectors for such applications including: early detection of wildfires; tracking pesticides drift in agricultural settings; tracking dispersion and transport of air toxins and pollutants in civilian and military settings; and detecting emissions and leaks in industrial settings. Lidar has already successfully penetrated a range of markets including range finders, speed monitors, 3D imaging and surveying systems, cloud ceiling height measurement at airports and weather centers, and most recently for remote wind measurements in wind energy applications. Successful introduction of laser radar systems to new markets can have significant economic, safety and health impacts.This I-Corps project capitalizes on compact eye-safe infrared lidar technology developed for remote characterization of atmospheric aerosols or target trace gases with high sensitivity. The systems utilize robust infrared laser transmitters such as semiconductor lasers, fiber lasers, or quantum cascade lasers, operating at eye-safe levels, and yet achieving high detection sensitivities. Because these sources are invisible to the human eye, they do not interfere with operators of machinery or aircraft and can be broadly deployed. The systems are built on a rigid carbon fiber platform to add to their robustness in a broad range of ambient temperatures. The lasers operate in the pulsed mode with pulse duration in the nanosecond range and at high pulse repetition rates to tens of kilohertz. The lidar receiver section employs state-of-the-art infrared detectors together with hardware and software signal processing to achieve required performance levels.

该I-Corps项目的更广泛的影响/商业潜力是通过引入红外和眼睛安全的激光雷达（LIDAR）技术来减少或消除财产的损失/损失，并保护公共健康和安全，以实现高灵敏度远程羽状表征。 该技术有可能满足此类应用的各种客户领域，包括：早期发现野火；在农业环境中跟踪农药漂移；在平民和军事环境中跟踪空气毒素和污染物的分散和运输；并检测工业环境中的排放和泄漏。 LIDAR已经成功地渗透到了包括范围检测器，速度监视器，3D成像和测量系统，机场和气象中心的云天花板高度测量以及最近的风能应用中远程风能测量的云高度测量。成功将激光雷达系统引入新市场可能会产生重大的经济，安全和健康影响。该I-Corps项目大写，可用于紧凑的眼睛安全红外激光雷达技术，用于远程表征大气气溶胶或具有高灵敏度的目标痕量气体。 该系统利用强大的红外激光发射器，例如半导体激光器，纤维激光器或量子级联激光器，在眼部安全水平上运行，但可以达到高检测敏感性。 由于这些来源对人眼是看不见的，因此它们不会干扰机械或飞机的操作员，并且可以广泛部署。 该系统建立在刚性碳纤维平台上，以在广泛的环境温度下增加其稳健性。 激光在脉冲模式下以脉冲持续时间在纳秒范围内运行，并以高脉冲重复速率对数十千霍兹进行工作。 LIDAR接收器部分采用最先进的红外探测器以及硬件和软件信号处理，以达到所需的性能水平。
