Announcements (Updated 7 Dec 2014)

(7 Dec 2014) In Problem 3 on the final, I'm looking for a relationship between depth of field and resolution in part 3.1, and not actual numbers. In 3.2, you need to pick a working depth, or else design a system with a movable lens so that the working depth can be varied.

(3 Dec 2014) The last homework assignment is canceled. We don't have enough time for it.

(3 Dec 2014) The Final Exam is now posted. It is due in one week, on 10 December, at 23:59:59 Eastern Standard Time.

(12 Nov 2014) Here are some statistics on the midterm. Overall, it looks like it was a bit harder than I'd planned. I generally don't make any "adjustments" on grades during the term. I prefer to do so at the end of the course, taking everything into account.

For each problem, I sent to every student, (a) the problem number, (b) the score (out of 25), and a short comment on what was right and what was wrong. The last line is the total score out of 100.

I will post solutions shortly.

(9 Nov 2014) The homework deadline scheduled for next Tuesday will be extended by one week. I will complete the lectures on Chapter 7 Friday.

(26 Oct 2014) I have posted some project ideas.

(19 Oct 2014) A couple of hints on the exam:

In Problem 3, the mirrors are turned by the motors that are shown in gray near the arrows. One generates a horizontal scan and the other generates a vertical scan. There is a subtle difference between the two, which is the "tricky part."

In problem 1, the auxiliary system makes a "virtual pinhole and card" at a location 19.2 cm after the auxiliary lens vertex. That plane is conjugate to the real pinhole and card somewhere on the left of the lens. You don't care exactly where the real card is, as long as it's conjugate to this position. If the light returning through the lens under test focuses at the "virtual card" it will then focus at the real card, because those two planes are conjugate.

(16 Oct 2014) There were a couple problems with the exam. There's a new version posted at the same location , with changes in red. Among other things, Figure 2 is now correct. The other points were mainly to clarify some issues raised by one of the students.

(14 Oct 2014) It looks like I made a mistake in the Coddington shape factor, q. Looking at slide 2r4-40 in the slides for Chapter 2, I state that our sign convention is that radii of curavature are positive for surfaces that are convex when viewed from the source. Thus, for a biconvex lens, r_1 is positve and r_2 is negative. Checking slide 2r4-46, the lensmaker's equation is based on this sign convention. If it were not, then for a symmetric biconvex thin lens, the optical power would go to zero. Again, on 2r4-44, for the powers of the two surfaces to be equal with n'=n, the radii must have opposite signs. In the slides for Chapter 5, slide 5r1-28 has a variation of the same equation at the top. However, for a biconvex lens, the q is not zero.

It appears that I've switched sign conventions in Chapter 5, and this is something I need to correct. In the notation I carefully defined in Chapter 2, q=(r_1+r_2)/(r_1-r_2). Thus for a symmetric biconvex lens r_2 = -r_1, and q=0. I'm confident that the relationships between p and q are still correct. I believe everything works out right in the plots too (I'll have to check them all now to be sure), so I think the damage is limited.

Alas, the statement on 2r4-40 is hereby proven correct; "Check the equations carefully."

(14 Oct 2014) The midterm exam is now posted. Please follow the directions on the .pdf file and submit through Blackboard by the deadline, next Tuesday, 21 Oct. at 23:59:59.

(29 Sep 2014) The dropbox for HW 2 has been created. I haven't a clue why I made the due date 11 October. First of all, it's a Saturday and I don't usually do that. Second, it's only 3 days before HW 3 is due, which doesn't make sense. My best guess is that I intended it to be due 7 October. Because it's listed as 11 October in the syllabus, I'm keeping that due date on the dropbox, but keep in mind that you will have very little time for HW3 if you wait that long.

(28 Sep 2014) There is an interesting article on a very simple form of optical cloaking that uses geometric optics principles we have just studied. Thanks to one of my summer students, Langston Archer, for sending me this link. http://www.rochester.edu/newscenter/watch-rochester-cloak-uses-ordinary-lenses-to-hide-objects-across-continuous-range-of-angles-70592/ There is good potential for a term project here.

(16 Sep 2014) The dropbox for HW 1 has been created on Blackboard. Please submit your homework there electronically. The problems for Chapter 1 and 2 (HW1) are due 23 September.

If you are tempted to use a website as a citation in a report or paper, please look at this site first.

(10 Sep 2014) I have a conflict tomorrow, Thursday, and will not be able to hold office hours. Please email me for alternative times.

(8 Sep 2014, 8:11pm) If the video is not clear, you can listen to the voice and view the slides with your favorite pdf viewer. There is some uncertainty as to how they will display. Hopefully the problems will be cleared by tomorrow's lecture.

(8 Sep 2014, 3:28pm) Now they have recovered most of the lecture and it is posted as Mon, Sep 08, 12 39 PM. There may be some quality issues, so let me know if you can't read (or hear) something.

(8 Sep 2014, 1:20pm) It appears that the original file was corrupted and they are not going to be able to completely recover it. They have a backup audio file, which they are trying to synchronize with the presentation material. I have also requested that they obtain a copy of the lecture from 2 years ago for you to view. If necessary, I'll re-do the lecture later this week. Watch here for more updates.

(8 Sep 2014) The Tegrity support people have been having systemic problems such as the one reported last night. They think they have recovered the original files from the computer in the classroom that was used for recording, and, if all goes well, will have them uploaded within 2 to 3 hours (i.e. early afternoon today). I've asked them to keep us updated as to their progress, and I'll report anything I hear on this site. Meanwhile, I encourage everyone to go on the discussion boards and introduce yourselves.

(7 Sep 2014) There appears to be a problem with the Tegrity recording of Lecture 1 online. I believe I recorded 97 minutes, and I think as of Friday afternoon it was all there, but at the moment, one student has reported that only the first 5 minutes are there. I checked and found the same problem. I have a request in to the people responsible for the recordings, and I'll post their answer here as soon as I get it. For your information, I went over the Syllabus and  Lecture Notes 1 - Introduction as far as page 18. I suggest you bring the remaining pages of Lecture 1 to class (or have them ready when you watch). I recommend taking your own notes in the blank areas of my presentation material.

(5 Sep 2014) I have opened the discussion boards on Blackboard. Please log in and introduce yourself.

(5 Sep 2014) I have been informed that the IT people will be checking the uploads to identify any problems. This may delay your viewing up to 24 hours. Please let them (and me) know if you see any problems or if you can't view the material after 24 hours.

(5 Sep 2014) The class is located in 202 Kariotis. Streaming video will be available about 2 hours after the conclusion of the class.

(3 Sep 2014) Welcome to Optics for Engineers. The slides for this course will be updated versions of those used in 2012. Those are located at http://www.ece.neu.edu/courses/eece7105/2012fa/index.html
