This Small Business Innovation Research (SBIR) Phase I project is in the general area instrumentation development in the subfield of infrared spectrometry. Conventional methods of infrared (IR) spectroscopy utilize either a small throughout (IR flux) optical element for dispersion followed a detector (or array), or a large throughout, scanning interferometer followed by a detector. A new, smart detector design is proposed here for accomplishing transform spectroscopy of infrared light directly on the detector chip itself. The new method is a large throughput transform technique which incorporates the multiplex advantage without requiring a mechanically scanned interferometer. This new spectrometer is potentially very small, compact, and rugged, especially if it is fabricated on a silicon wafer substrate, as is planned (i.e., a spectrometer on a chip). This opto- electronic device structure can also be adapted to other IR instrument technologies. During this Phase I project these investigators will make a first loop on the full design and concept testing for the graded interference-filter spectrometer device. The concept for this new device for IR transform spectroscopy arises out of several areas of strength within the research staff at Advanced Fuel Research, Inc., hence the potential for success is large.

这个小型企业创新研究(SBIR)第一阶段项目是在红外光谱分析的子领域仪器开发的一般领域。传统的红外(IR)光谱方法要么利用小通过率(IR通量)光学元件在探测器(或阵列)之后进行色散，要么利用大通过率扫描干涉仪在探测器之后进行色散。提出了一种新的智能探测器设计方案，直接在探测器芯片上实现红外光的变换光谱。这种新的方法是一种大吞吐量变换技术，它结合了多路复用的优势，而不需要机械扫描干涉仪。这种新的光谱仪可能非常小巧、紧凑和坚固耐用，特别是如果它按照计划在硅片衬底上制造的话(即，芯片上的光谱仪)。这种光电器件结构也可以适用于其他红外仪器技术。在这个第一阶段的项目中，这些研究人员将对分级干涉滤光片光谱仪装置的全面设计和概念测试进行第一次循环。这种用于红外变换光谱的新设备的概念源于高级燃料研究公司研究人员的几个优势领域，因此成功的潜力很大。
