Intellectual MeritThis is a collaborative project between an NSF Engineering Research Center for Technologies for Health and the Environment (MIRTHE) and Physical Sciences Inc. (PSI), a company that is a world-renowned leader in the research and development of laser chemical sensing technologies. The proposal focuses on developing a new, compact, cryogen-free mid-infrared hard-target LIDAR (laser detection and ranging) technology for remote spectroscopic chemical sensing that will target atmospheric methane. The proposed system will be based on a new chirped laser dispersion spectroscopy (CLaDS) technique, recently invented by the PI, who is a researcher at the MIRTHE ERC. The proposal will develop a new remote sensing technology that is capable of atmospheric CH4 monitoring and will provide significant improvements over the current state-of-the-art. Present concentration in North America range from 1600 to 2200 parts per billion by volume (ppbv). Unfortunately, it is difficult to fully quantify its emission rates and location of sources and sinks using existing methane monitoring instrumentation. Thus technologies that enable remote sensing of natural and anthropogenic methane emissions are needed for accurate source and sink assessments of this important greenhouse gas. The new sensor system, CLaDS, is based on measurement of resonant molecular dispersion and provides unique capabilities for remote chemical detection (i.e. immunity to optical power fluctuations). The proposed instrumentation will also take advantage of another core MIRTHE technology; quantum cascade lasers (QCLs). QCLs give an access to the mid-infrared region of electromagnetic spectrum between ~3 and 16 ìm where most chemical compounds in the gas phase (including methane) possess their strongest fundamental ro-vibrational absorption features. As a result, detection at mid-IR wavelengths enables ultra-high sensitivity detection of trace-gases. Broader ImpactUltra-sensitive, fast, in-situ molecular remote detection has a large number of applications in environmental studies, industrial emission monitoring and security. Therefore new discoveries and scientific advancements in this field integrated with a comprehensive educational program will provide an excellent training for the new generation of scientists and engineers as well as have a strong impact on the well being of society. The versatility of the project provides a full spectrum of education and training opportunities integrated with the research goals and specifically addresses career development goals at each academic level from high school students to post-doctoral researchers. Participation of a graduate student and a post-doc is planned within the budget of this project. The engagement of undergraduate students will be provided through other programs including a strong MIRTHE Research Experience for Undergraduate (REU) Program.

知识分子绩效是NSF卫生与环境技术技术研究中心（MIRTHE）和物理科学公司（PSI）之间的合作项目，该公司是一家在激光化学感应技术研究和开发领域的世界知名领导者。该提案着重于开发一种新的，紧凑的，无低温的中红外硬靶刺；用于远程光谱化学敏感性的技术将靶向大气甲烷。拟议的系统将基于新的Chirped激光色散光谱（Clads）技术，该技术最近是由PI发明的，PI是Mirthe ERC的研究人员。该提案将开发一种新的遥感技术，该技术能够进行大气CH4监测，并将对当前最新面临提供重大改进。目前的北美集中度范围从1600至2200份零件（PPBV）。不幸的是，很难使用现有的甲烷监测仪器充分量化其排放率以及来源和下沉的位置。需要对天然和人为甲烷排放的远程灵敏度的技术来准确地评估这种重要的温室气体。新的传感器系统Clads基于谐振分子色散的测量，并为远程化学检测提供了独特的功能（即对光功率波动的免疫力）。拟议的仪器还将利用另一个核心米尔特技术。量子级联激光器（QCLS）。 QCL可以进入〜3至16确实之间的电磁光谱中的中红外区域，其中大多数化合物在气相中（包括甲烷）具有强大的基本RO振动滥用特征。结果，在IR波长的检测可以实现痕量胶囊的超高灵敏度检测。更广泛的影响量敏感的，快速的，原位的分子远程检测在环境研究，工业排放监测和安全性中具有大量应用。因此，与全面的教育计划相结合的该领域的新发现和科学进步将为新一代的科学家和工程师提供出色的培训，并对社会的福祉产生强大的影响。该项目的多功能性提供了与研究目标相结合的全面教育和培训机会，并专门针对从高中生到博士后研究人员的每个学术层面的职业发展目标。计划在该项目的预算范围内，计划的研究生和DOC的参与计划。本科生的参与将通过其他计划提供，包括强大的Mirth本科生（REU）计划。
