*** 9661412 Deliwala This Small Business Innovation Research Phase I project to be carried out by Science Research Laboratory (SRL) proposes to develop a rugged, inexpensive, alignment-free, optical interferometer that will be integrated with a course of experiments illustrating both the basic concepts of wave interference and the application of high-precision measurements in many disciplines. The instrument will be capable of optical path resolutions of better than 1 nm, which is one to two orders of magnitude more sensitive than typical instruments used for instruction. The scope of possible experiments is vast, ranging from measurement of position to nanometer precision to the photoacoustic detection of trace constituents for environmental monitoring. The interferometer may be used by high schools or science and engineering departments at the under graduate level. The inherent flexibility and rich history of the device will make it an ideal tool for bringing excitement of modern science and engineering to students. Phase I will develop the design of a laboratory interferometric instrument as well as a coherent strategy for experiments, curricula and pedagogic methods. In the next phase of the research, SRL will construct a prototype instrument and produce a large database of experiments together with guidelines to integrate them into curricula. The instrument is primarily targeted at the educational market proffering to students what is not now available; namely, an affordable research-grade instrument. Variations on the instrument will be developed for dedicated commercial applications such as high-frequency measurements of gas density fluctuations, electron density of plasmas, detection of trace chemical species, and femtosecond spectroscopy. ***

* 9661412 Deliwala 由科学研究实验室（SRL）进行的小企业创新研究第一阶段项目提出开发一种坚固，廉价，无磨损的光学干涉仪，该干涉仪将与一系列实验相结合，说明波干涉的基本概念和高精度测量在许多学科中的应用。 该仪器的光程分辨率将优于1 nm，比用于教学的典型仪器灵敏一到两个数量级。可能的实验范围很广，从位置测量到纳米精度，再到环境监测中痕量成分的光声检测。 该干涉仪可用于高中或科学和工程系在研究生以下的水平。 该设备固有的灵活性和丰富的历史将使其成为为学生带来现代科学和工程兴奋的理想工具。 第一阶段将设计一种实验室干涉测量仪器，并为实验、课程和教学方法制定一项协调一致的战略。 在研究的下一阶段，SRL将构建一个原型仪器，并制作一个大型实验数据库，以及将其纳入课程的指导方针。 该仪器主要针对教育市场，向学生提供现在无法获得的东西，即负担得起的研究级仪器。 该仪器的变化将被开发用于专门的商业应用，如气体密度波动的高频测量，等离子体的电子密度，痕量化学物质的检测和飞秒光谱。 ***
