Development of a Fiber Optic Infrared Spectrograph with Focal Plane Array Detection for Studying Materials during Processing and for use in Graduate/Undergraduate Education

0076017Rabolt这个GOALI提案涉及特拉华州大学和杜邦公司研发实验室，由MPS多学科活动办公室和DMR材料研究计划仪器共同资助。该奖项支持光纤红外光谱仪的开发和建造，该光谱仪使用InSb焦平面阵列探测器，因此没有移动部件。FTIR在过去30年中的巨大成功直接归因于干涉测量仪器提供的多路复用和吞吐量优势。然而，由于与这种仪器的扫描机构耦合的升高的噪声水平，在过程环境中使用这种扫描仪器可以显著减少（如果不是消除的话）这些优点。随着光学设计和材料技术的进步，色散仪器现在可以在通量方面与FTIR竞争，同时保持多重优势。在零运动部件的情况下，可以通过摄谱仪设计对噪声进行时间平均。出于这个原因，我们认为，这样一个便携式色散焦平面阵列光谱仪可能会提供显着的优势，在一个过程中的环境中，样品波动是common.This GOALI建议，其中涉及特拉华州和杜邦公司的研究和开发实验室的大学，是由多学科活动的MPS和DMR的材料研究计划仪器办公室共同资助。该奖项支持在特拉华州大学材料科学与工程系建造“首台”光纤红外光谱仪。这是一个强大的分析工具，没有移动部件。它采用超快焦平面阵列探测器，用于实时研究不同的化学物质。该仪器项目的成功将使整个系列的分析工具，将发现在线过程监测，环境保护和法医科学的应用。光纤和焦平面阵列的使用使得这种红外仪器便携，允许它被带到感兴趣的位置，例如。例如，在一个实施例中，聚合物薄膜的生产线。此外，工业合作伙伴参与该项目是一个很好的例子，说明一个强大的研发项目如何为学生提供宝贵的经验，他们将花费部分时间在工业实验室进行研究，为他们提供额外的劳动力准备技能。参与该项目的学生和博士后研究员将接触到最先进的仪器和现实生活中的工业环境，这两者都是工程职业成功的重要教育组成部分。

0076017Rabolt This GOALI proposal, which involves the University of Delaware and Dupont Corporate Research and & Development Lab, is jointly funded by the Office of Multidisciplinary Activities in MPS and the Instrumentation for Materials Research program in DMR. The award supports the development and construction of a fiber-optic IR spectrograph that uses an InSb focal plane array detector and, as such, has no moving parts. The dramatic success of FTIR over the last 30 years is directly attributable to the multiplex and throughput advantages offered by interferometric instrumentation. However the use of such scanning instruments in a process environment can significantly reduce if not eliminate these advantages, due to the elevated noise level which couples with the scanning mechanism of such instruments. With the advances in optical design and material technology, dispersive instruments can now compete with FTIR in terms of throughput while keeping the multiplex advantage. With zero moving parts, the noise can be time-averaged by the spectrograph design. For this reason we believe that such a portable dispersive focal plane array spectrograph may offer significant advantages for infrared spectroscopy in a process environment where sample fluctuation is common.This GOALI proposal, which involves the University of Delaware and Dupont Corporate Research and & Development Lab, is jointly funded by the Office of Multidisciplinary Activities in MPS and the Instrumentation for Materials Research program in DMR. The award supports the construction of a "first-of-its-kind" fiber optic IR spectrograph at the Materials Science and Engineering Department of the University of Delaware. This is a powerful analytical tool with no moving parts. It employs an ultrafast focal plane array detector for real-time studies of different chemical species. The success of this instrumentation project will enable an entire family of analytical tools that will find applications in on-line process monitoring, environmental protection and forensic sciences. The use of fiber optics and a focal plane array makes this infrared instrument portable, allowing it to be brought to the location of interests, e. g., to a production line of thin polymer films. In addition, The involvement of an industrial partner in this project is a good example of how a strong R & D project can provide a valuable experience for students who will spend part of their time doing research in an industrial laboratory, providing them with additional work-force-ready skills. The students and postdoctoral fellows involved in this projects will be exposed to both the state-of-the-art instrumentation and real-life industrial environment, which are both crucial educational components for a successful career in engineering.
