Small Business - ERC Collaborative Opportunity to develop an instrument for trace detection of O2 using a high-finesse prism optical cavity and the Faraday Effect

智能优点：在该项目中，提出了一种新的全光学CE-FRS检测方案，以减少对样品气体进行任何化学处理的需求，而目前现有的痕量氧传感仪器通常需要对样品气体进行任何化学处理。该项目将利用泰格光学公司的腔增强技术开发和商业化的独特能力，以及由MIRTHE开发和演示的基于FRS的新传感技术。首先，将在传统的两镜高精细度腔的基础上研究一个概念验证原型系统，该腔配备了用于信号提取的定制FRS光学元件。最重要的是，该研究还将探索利用泰格光学公司专有的高精细度光学棱镜腔技术实现CE-FRS的可能性。这项独特的技术将允许CE-FRS与标准的CW-CRDS在同一商业仪器中结合实施，从而允许同时对顺磁和抗磁分子进行灵敏的宽带检测。建议的技术将消除常规维护问题、化学转化的不确定性和其他电化学系统或间接传感技术的典型缺点。建议的基于激光的直接检测在需要全天候连续监测的工业应用中以及在分析器通常位于具有基本基础设施的偏远位置的环境应用中提供了显著的优势。广泛的影响：CE-FRS方法的开发将开启对许多其他顺磁物种的灵敏监测的可能性。该方法适用于燃烧和大气化学中NO、NO2、OH、HO2和CH等痕量自由基浓度的实时监测。在许多情况下，虽然这些自由基的存在是已知的，但由于缺乏现场监测能力，反应率和丰度并不是很清楚。基于直接激光的方法可以为监测环境监测、工业过程控制或燃烧诊断等广泛应用中的痕量自由基提供一种新的工具。因此，这一领域的科学和工程进步与全面的教育计划相结合，以解决从高中生到博士后研究人员的每个学术级别的具体职业发展目标，将为新一代提供极好的培训

Intellectual Merit :In this project a new fully optical CE-FRS detection scheme is proposed to mitigate needsfor any chemical treatments of the sample gas that is usually required with currently availableinstrumentation for trace oxygen sensing. The project will leverage unique capabilities ofdevelopment and commercialization of cavity enhanced technologies by Tiger Optics and thenew sensing technology based on FRS developed and demonstrated by MIRTHE. Initially a proof-of-conceptprototype system will be investigated based on a conventional two mirror high-Finesse cavityequipped with a custom FRS optics for signal extraction. Most importantly the proposed researchwill also explore the possibility of implementing CE-FRS using the Tiger Optics proprietaryhigh-Finesse optical prism cavity technology. This unique technology would allow CE-FRS tobe implemented in combination with standard cw-CRDS in the same commercial instrument, permittingsensitive broadband detection of paramagnetic and diamagnetic molecules simultaneously. Theproposed technology will eliminate routine maintenance issues, chemical conversion uncertaintyand other disadvantages typical for electrochemical systems or indirect sensing technologies.The proposed direct laser-based detection provides significant advantage in industrial applicationswhere 24-7 continuous monitoring is required and in environmental applications where analyzersare often situated in remote locations with basic infrastructure.Broader Impacts :Development of a CE-FRS method will open up possibilities for sensitive monitoring of manyother paramagnetic species. This method will be suitable for real-time monitoring of traceconcentrations of radicals involved in combustion and atmospheric chemistry, i.e. NO, NO2,OH, HO2, and CH. In many cases, while the presence of these radicals is known, the reactionrates and abundances are not well known due to the lack of in situ monitoring capabilities.A direct laser-based method can provide a new tool for monitoring trace-radicals in a widerange of applications such as environmental monitoring, industrial process control or combustiondiagnostics. Therefore scientific and engineering advancements in this field integrated witha comprehensive educational program addressing specific career development goals at each academiclevel from high school students to post-doctoral researchers, will provide an excellent trainingfor the new generation
