# Design of High-Performance Optical Systems

### Description

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.

### What you will learn

Chromatic Aberrations

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.

Ray Aberrations

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.

Field Curvature and Distortion

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.

Techniques for Reduction of Aberrations

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.
