MRI: Development of middle infrared optical nose

Mirov0521036拟议项目的目标是开发能够分析给定气体样品的仪器，具有完全的化学特异性、最终的灵敏度和实时速度。这些具有挑战性的需求将通过应用基于高功率、超宽和快速可调的中红外激光光源的光学检测方法以及兼容的传感和信号增强技术来同时满足。所提出的激光光学鼻子工作在分子指纹区(2-20m)的光谱范围内，将直接获得生物、医学、环境和化学相关的痕量气体分子的最强吸收线，有望在许多不同的科学和技术领域具有广泛的技术相关性。该开发项目将把激光科学家、光学传感器和光谱学专家、环境科学家、分子生物学家、化学家和生物化学家以及生物医学研究社区聚集在一个跨学科研究和教育的令人兴奋的环境中，并将提供机会了解生命过程和与生物医学、环境监测和反恐相关的有毒和爆炸材料探测方面的重要新发现。这种灵敏的光学鼻子仪器将有助于解决当前状态和地区性环境问题和关切(即，安尼斯顿陆军化武焚化炉存在的问题)。在国家舞台上，这些传感器系统将提供独特的痕量气体检测能力，对石油勘探、环境监测、大气研究、食品生产以及爆炸物和生物和化学有毒物质的现场无损检测和表征至关重要。这一能力将有助于在恐怖分子部署之前的尽可能早的阶段(例如机场安检)发现危险物质，并可能避免未来发生化学和生物恐怖袭击。开发新的有毒物质检测和鉴定产品和技术可能会催生新的剥离公司，并帮助阿拉巴马州的行业从传统的重型制造业工作演变为需要更高学历和更高技能的劳动力的面向未来的环境科学和高科技传感相关工作。

Mirov0521036The objective of the proposed project is the development of instrumentation capable ofanalyzing a given gaseous sample with a full chemical specificity, with ultimate sensitivity, and real time speed. These challenging demands will be simultaneously satisfied by applying optical detection methods based on high-power, ultra-broadly and rapidly tunable mid-IR laser sources, and compatible sensing and signal enhancing techniques. The proposed laser optical nose operating over the spectral range of molecular fingerprint region (2-20 ?m) will give direct access to the strongest absorption lines of biologically, medically, environmentally, and chemically relevant trace gas molecules and is expected to have a broad technological relevance for many different fields of science and technology. The development project will bring together laser scientists, optical sensor and spectroscopy experts, environmental scientists, molecular biologists, chemists and biochemists, and biomedical research communities in an excitingenvironment of interdisciplinary research and education, and will provide the opportunity forunderstanding life processes and important new discoveries in biomedicine, environmental monitoring, and Counter-Terrorism related detection of toxic and explosive materials.Such sensitive optical nose instrumentation will help to address current state and regionalenvironmental problems and concerns (i.e. such as what exists at the Anniston Army Depot chemical weapon incinerator). In the national arena, these sensor systems will give a unique capability of trace gas detection essential for oil prospecting, environmental monitoring, atmospheric research, food production, and on-site nondestructive detection and characterization of explosives, and biological and chemical toxic substances. This capability will help to detect dangerous agents at the earliest possible stage (e.g., airport screening) before deployment by terrorists, and may avoid future chemical, and biological terrorist attacks.The instrumentation to be developed has the potential to become the major resource for trace gasanalysis for the state and region. The development of new toxic detection and characterizationproducts and technologies may lead to new spin-off companies, and help Alabama-based industries evolve from traditional heavy manufacturing jobs to future-oriented environmental science and high-tech sensing-related jobs requiring a more highly educated and skilled workforce.
