I hope that many people will find this material useful. I am making it available here in a very open form for the convenience of my students. In the spirit of academic openness, anyone is welcome to print a copy for personal use. However, please do not present it in any public venue or alter it in any way without my permission.

 Textbook: Optics for Engineers The text for this course is my book Optics for Engineers. Click on the book or the link above for more information from my publisher, CRC Press. Handouts of my notes, based on the book, will be posted here (as pdf files) as I complete them.

(24 Apr 2017) Hints on the Take--Home Exam: First, because of my bad handwriting...
The green part says NA_R = \sin\theta_R (R is for "reference". The red is NA=\sin\theta with no subscript for the signal. Incident light is polarized at 45 degrees with respect to the quarter--wave plage (QWP) axes. The diagonal line is a polarizing beam splitter.
The line "abs(E+exp(1j*k*sin(up)*x)).^ 2" produces the interference pattern of the original "object" field with a tilted plane wave. This gives information like we saw in the optical testing section of Chapter 7. When you modify the pupil in solving the problem, you are trying to create an approximation to this situation, using just the signal beam, with spatial filtering. The result will not be perfect, but hopefully will come close if you pick the right parameters.

(20 Apr 2017) The Matlab Code is now posted. Sorry I forgot that. I chose to give only two problems because I know you are busy with the project and likely with other courses as well.

(19 Apr 2017) The final is now posted.

(16 Apr 2017) Some comments on the projects:
Scope: The project is equivalent in weight to one of the exams or all of the homework. Plan to spend a similar amount of time on it.
Submitted Material: Please submit one .pdf file in report format. You may include your code in a .zip file with it if you like, but that is optional. The report should clearly show what you did.
Date: I can accept the project report as late as Thursday the 27th. That will give me time to grade these before grades are due the following Monday.

(13 Apr 2017) The final homework is problem 7.1, 8.1, and 9.1, due on Friday the 21st. The exam will be distributed on Wednesday the 19th and due on Friday the 28th.

(29 Mar 2017) Here is a list of possible Projects that you might consider. Feel free to pick your own, but this has some suggestions and will also give you an idea of the right size. homework for Chapter 7 is just the first two problems, and I'd like to get it Thursday if possible. I can be a little flexible at this point.

(13 Mar 2017) Chapter 5 homework is officially due today, but I'll accept it Thursday. For Chapter 6, the homework assignment is only problems 1 and 2. I'll work on a plan for Chapter 7.

The Annual Student Pipeline Industry Roundtable Event (ASPIRE) will be held on Thursday, March 16, 2017 from 12:00 – 5:00pm at Northeastern University, Boston. The ASPIRE is hosted by the ALERT (Awareness and Localization of Explosives-Related Threats) & Gordon-CenSSIS (The Bernard M. Gordon Center for Subsurface Sensing and Imaging Systems). ASPIRE provides an optimum setting for dialogue among members of the academic, industrial and government communities and also provides networking opportunities for students looking for internships, co-op opportunities and full-time jobs in the next ~6 months. Please note that most of the industry and government partners who are attending are restricted to hire only U.S. citizens.

If you are interested in attending, please reach out to Melanie Smith at m.smith@northeastern.edu.

(26 Feb 2017) The pixel size for problem 1.3 is 7.4 micrometers.
Homework for Chapter 5 will be due after break. I don't want to interfere with your time on the take-home exam.

(23 Feb 2017) The take--home exam is posted.

(8 Feb 2017) Reminder: Northeastern University is closed tomorrow, Thursday, and all classes are cancelled.

(26 Jan 2017) A numerical example for Chapter 2 is at html/ch2examples.html.

(20 Jan 2017) The first homework assignment is to include all the problems of Chapter 1 and Problem 2.1.

(18 Jan 2017) I've made some minor changes to slides2. The correct version should have page numbers that begin with slides2r5. If you have already downloaded the previous version you can work well with it. There are only a couple of changes.

(8 Dec 2016) Welcome to Optics for Engineers. This is the undergraduate version of the course. We'll cover some of the same material as the graduate course, but omitting some sections and reducing the scope of others. Here's a link to the graduate course website from the last time it was taught.
