课程名称：光学效率与分辨率 课程概述：本课程可作为学术学分选修，课程编号为ECEA 5601，是科罗拉多大学博尔德分校电气工程硕士学位的部分课程。光学仪器使我们能够看到世界，从矫正眼镜到医疗内窥镜，再到手机摄像头及轨道望远镜。本课程将教您使用简单的数学和图形技术设计这些光学系统。前一课程中的一阶光学系统设计对于光学成像系统的初步设计非常有用，但并不能预测系统的能量和分辨率。本课程讨论高斯光束和非相干源的强度传播，并介绍设计所需视场和分辨率的光学系统所需的数学背景。您还将学习如何使用行业标准的设计工具OpticStudio（由Zemax提供）分析光学系统的这些特性。 课程大纲： 1. **高斯光束的几何光学**：介绍使用光线进行的一阶光学系统设计，着重讨论高斯光束及其在成像系统中的演变。 2. **麦克斯韦方程组**：提供光学系统电磁场全描述的背景，包括平面波和球面波的描述，以及反射和折射的正式处理。 3. **脉冲响应与传递函数**：介绍傅里叶光学的基础，讨论影响成像系统分辨率的傅里叶变换，并区分相干与非相干系统以及脉冲响应与传递函数。 4. **有限孔径光学**：应用前面模块中讨论的瞳孔和分辨率的概念，阐述如何找到系统的瞳孔和窗口，并讨论其对成像特性的影响。 5. **辐射度测量**：探讨设计光学系统时如何评估光的通过量，从分辨率转向讨论光学系统中每个点的光强度，进入辐射度学的领域。 通过本课程，您将掌握光学系统设计的关键方法与工具，为更深入的光学工程打下坚实的基础。
Name:Geometrical Optics for Gaussian Beams
Description:First order optical system design using rays is useful for the initial design of an optical imaging system, but does not predict the energy and resolution of the system. This module introduces Gaussian beams, a specific example of how the shape of the light evolves in an imaging system.
Name:Maxwell's Equations
Description:This module provides the background for the full electro-magnetic field description of optical systems, including a description of plane and spherical waves and a formal treatment of reflection and refraction from this perspective. We start out with a quick review of the mathematical background for this description. This will be fairly short, but you may want to spend some more time reviewing these concepts on your own if you have not seen them for a while.
Name:Impulse Responses and Transfer Functions
Description:This module provides an introduction to the basics of Fourier Optics, which are used to determine the resolution of an imaging system. We will discuss a few Fourier Transforms that show up in standard optical systems in the first subsection and use these to determine the system resolution, and then discuss the differences between coherent and incoherent systems and impulse responses and transfer functions in the second subsection. We will wrap up with a discussion of these concepts using OpticStudio.
Name:Finite Aperture Optics
Description:This module takes the concepts of pupils and resolution that we have discussed in the previous modules and works through how to apply them to our first-order optical design systems. We start with a description of how to find the system pupils and windows, then move on to a discussion of how that affects the imaging properties of this system, and finally return to the Lagrange invariant and its utility in optical system design.
Name:Radiometry
Description:One of the main questions you ask when designing an optical system is "How much light can I get through the system?" In this last section of new content for this course, we move from talking about resolution to talking about the amount of light we expect at each point in the optical system, a field of study called radiometry.
This course can also be taken for academic credit as ECEA 5601, 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 will teach you how to design such optical systems with simple mathematical and graphical techniques. The first order optical system design covered in the previous course is useful for the initial design of an optical imaging system but does not predict the energy and resolution of the system. This course discusses the propagation of intensity for Gaussian beams and incoherent sources. It also introduces the mathematical background required to design an optical system with the required field of view and resolution. You will also learn how to analyze these characteristics of your optical system using an industry-standard design tool, OpticStudio by Zemax.
