课程名称：高性能光学系统设计 课程概述：本课程可以作为学分课程参加，课程代码为ECEA 5602，是CU Boulder电气工程硕士学位的一部分。光学仪器是我们观察世界的重要工具，涵盖从矫正眼镜、医学内窥镜到手机摄像头及天文望远镜等。这门课程将扩展您对一阶、准轴系统设计及光学分辨率和效率的理解，引入实际透镜及其缺陷的概念。课程初始描述了不同波长在系统中的传播，随后探讨了在高角度、非准轴系统中出现的像差及其修正方法。课程结束时将讨论透镜以外的光学组件，并以人眼作为高性能光学系统的杰出例子进行讲解。由于高性能系统分析所需的数学工具相对复杂，本课程将更依赖于Zemax的OpticStudio软件，以便学生可以分析那些无法简单分析的复杂系统。 课程大纲： 1. **色差**：本模块将介绍如何从一阶近似转向实际透镜和不完美光学系统，描述不同波长在系统中的传播。 2. **光线样本的像差**：介绍光学系统中单色的各种缺陷及其成因，提供数学背景并识别常见的像差。 3. **场曲率和畸变**：继续讨论单色光学系统中的缺陷，引入场曲率和畸变，并总结三阶像差的成因及其数学工具描述。 4. **减少像差的技术**：讨论如何设计系统以限制之前讨论的各种像差。 5. **光学组件**：在最后一个模块中，转向其他常见光学元件，讲述透镜以外的光学元素，包括棱镜、GRIN透镜、衍射光学（如衍射光栅和Fresnel透镜），并重点介绍人眼作为关键光学元件。 本课程内容复杂，可能需要学生花费更多时间来掌握。
Name:Chromatic Aberrations
Description:We now move away from the first order approximations and into real lenses and imperfect optical systems. We begin with a description of how different wavelengths propagate through systems.
Name:Ray Aberrations
Description:This module introduces the many types and causes of monochromatic imperfections in optical systems. We begin with the mathematical background of the causes of aberrations, then introduce a number of common aberrations so that you may recognize them in your own systems.
Name:Field Curvature and Distortion
Description:This module continues to discuss monochromatic imperfections in optical systems. We introduce field curvature and distortion so that you may recognize them in your own systems and then summarize the causes and effects of 3rd order aberrations along with the mathematical tools to describe them.
Name:Techniques for Reduction of Aberrations
Description:The previous three modules have discussed the various types of aberrations you will find in your optical systems. We now move to how to design a system that limits those aberrations.
Name:Optical Components
Description:In this last module before the capstone, we change gears from aberrations, and discuss a number of other optical elements that are usual in systems other than lenses. We cover light shaping with prisms, GRIN lenses, diffractive optics such as diffraction gratings and Fresnel lenses. Then we finish with an important optical element to all of us - the human eye. This module covers a lot of material and may take you a bit longer than the others.
This course can also be taken for academic credit as ECEA 5602, part of CU Boulder’s Master of Science in Electrical Engineering degree. Optical instruments are how we see the world, from corrective eyewear to medical endoscopes to cell phone cameras to orbiting telescopes. This course extends what you have learned about first-order, paraxial system design and optical resolution and efficiency with the introduction to real lenses and their imperfections. We begin with a description of how different wavelengths propagate through systems, then move on to aberrations that appear with high angle, non-paraxial systems and how to correct for those problems. The course wraps up with a discussion of optical components beyond lenses and an excellent example of a high-performance optical system – the human eye. The mathematical tools required for analysis of high-performance systems are complicated enough that this course will rely more heavily on OpticStudio by Zemax. This will allow students to analyze systems that are too complicated for the simple analysis thus far introduced in this set of courses.
