Interdisciplinary (99)We are developing an undergraduate optics facility to serve as a center for optics instruction and promote an enhanced understanding of optics across several areas in the college of science and math at Cal Poly. The facility is being used in the teaching of upper division physics and chemistry courses and increasingly for student and faculty research projects. The theme of the laboratory is optical metrology. This ranges through interferometric measurement of solid body deformation, optical characterization of surfaces and laser spectroscopy and determination of atomic linewidths. Not only does this tie in with the Polytechnic nature of our university, but by thematically developing the facility we also demonstrate the unity and commonalties of optical methods. For example, the resolution of optical systems and the determination of object deformation by speckle interferometry are both essentially diffraction limited phenomena. For the laboratory we will adopt, modify, and develop new experiments. Experiments that will be adopted include plane wave interference [Catunda et. al. Am. J. Phys. 66, 548 (1998)] and photon counting [Kocyk et. al. Am J. Phys. 64, 240 (1996)] in physics and radiative properties of ruby [Shoemaker et. al. "Experiments in Physics Chemistry" 6th Ed., McGraw-Hill (1996)] in chemistry. Other experiments will be adapted and modified to suit our student body. For example, in chemistry, beginning with a known fluorescence quenching experiment of the uranyl ion by the chloride ion [Halpern "Experimental Physical Chemistry" 2nd Ed. Prentice Hall (1997)] this experiment will be expanded to include micellar systems [Almgren et. al. Langmuir 12, 3855 (1996)] which is of relevance to our biochemistry majors. Some well known experiments will be adapted and made more quantitative by the use of modern electronic cameras and computers. Thus, the Abbe-Porter experiment on spatial filtering [Hecht "Optics" 3rd Ed. Addison Wesley (1997)] will be modified so that students can acquire and measure the spatially filtered images. This optics laboratory will also permit us to develop new experiments for the physics and chemistry majors to make use of recent material and technical advances. For example, an experiment to study the modulation transfer function of a liquid crystal light valve will be developed which will allow students to become familiar with this important topic within the confines of a three-hour laboratory. Other experiments that will be developed within this facility include (in chemistry) vibrational modes of molecules which will be measured by Raman scattering and Fourier transform infrared spectroscopy and compared to computational models and (in physics) measurement of atomic hyperfine structure [Rao et. al. Am. J. Phys. 66, 702 (1998)] and atom trapping. Because of the rapid pace of change in optical science and technology and the growing application of optical techniques across the physical and chemical sciences it is difficult to establish and maintain an up-to-date facility containing the instruments of modern optics. However, much of this instrumentation is now used in the workplace or graduate school and it is necessary to provide training in optics to a large number of students from different disciplines. With this facility we will be able to give in-depth training to the students in 'optics' courses (e.g. laser applications), provide experiments for courses with large optics components (e.g. surface science) and give exposure to students in other areas. By centralizing the equipment and flexibly scheduling use of the laboratory we will be able to maximize its impact on the largest number of students and facilitate the interaction of faculty from different disciplines. We estimate that about 200 students/year will directly benefit from this facility. Also, because engineering students frequently take upper-division physics and chemistry classes, the facility will have an effect well beyond the College of Science and Mathematics.

跨学科（99）我们正在开发一个本科光学设施，作为光学教学中心，并促进在加州理工学院的科学和数学学院的几个领域的光学增强理解。该设施被用于高年级物理和化学课程的教学，并越来越多地用于学生和教师的研究项目。该实验室的主题是光学计量学。这包括固体变形的干涉测量、表面的光学表征和激光光谱学以及原子线宽的测定。这不仅与我们大学的理工性质有关，而且通过主题开发设施，我们还展示了光学方法的统一性和共性。例如，光学系统的分辨率和通过散斑干涉术确定物体变形本质上都是衍射极限现象。对于实验室，我们将采用，修改和开发新的实验。将采用的实验包括平面波干涉[Catunda et.等，Am. 66，548（1998）]和光子计数[Kocyk et.等人，Am J.Phys.64，240（1996）]在红宝石的物理学和辐射性质[Shoemaker et.《物理化学实验》第6版，McGraw-Hill（1996）]化学。其他实验将进行调整和修改，以适应我们的学生团体。例如，在化学中，从已知的氯离子对铀酰离子的荧光猝灭实验开始[Halpern“Experimental Physical Chemistry”第2版，普伦蒂斯霍尔（1997）]，该实验将扩展到包括胶束体系[Almgren et. Langmuir 12，3855（1996）]，这与我们的生物化学专业相关。一些众所周知的实验将被改编，并通过使用现代电子照相机和计算机变得更加定量。因此，阿贝-波特空间滤波实验[Hecht“Optics”3rd Ed. Addison Wesley（1997）]将被修改，以便学生可以获取和测量空间滤波图像。这个光学实验室还将允许我们为物理和化学专业的学生开发新的实验，以利用最新的材料和技术进步。例如，将开发一个研究液晶光阀的调制传递函数的实验，这将使学生在三小时的实验室范围内熟悉这一重要课题。其他实验，将在该设施内开发包括（在化学）分子的振动模式，将通过拉曼散射和傅里叶变换红外光谱测量，并与计算模型和（在物理学）原子超精细结构的测量进行比较[Rao et.等，Am. J.Phys.66，702（1998）]和原子捕获。由于光学科学和技术的快速变化以及光学技术在物理和化学科学中的日益应用，很难建立和维护包含现代光学仪器的最新设施。然而，这种仪器现在大部分用于工作场所或研究生院，有必要为来自不同学科的大量学生提供光学培训。有了这个设施，我们将能够在“光学”课程（例如激光应用）的学生进行深入的培训，为大型光学组件（例如表面科学）课程提供实验，并为其他领域的学生提供曝光。通过集中设备和灵活安排实验室的使用，我们将能够最大限度地提高其对最大数量的学生的影响，并促进来自不同学科的教师之间的互动。我们估计，每年约有200名学生将直接受益于这一设施。此外，由于工程专业的学生经常参加高年级的物理和化学课程，该设施的影响将远远超出科学和数学学院。
