Current syllabus is located on Canvas.
The Homework and Other Handouts:
The ray tracing homework can be found on Canvas. If you previously downloaded the file that was located here, be advised that you will need to get it off of Canvas. The two are not the same. You should be seeing a file that has a set of lines drawn on it for the optical axis and the lenses.
Optical design software activities and support:
- The landscape lens
- Fixing the crashing analysis in OSLO
- Optics (and software) reference (This is an excellent summary and tutorial on optics in general.)
- Various tutorials
If you are interested in trying the FRED optical engineering software please contact me and I'll give you our demo code and download. (You must be one of my students; anyone else should contact Photon Engineering directly.) FRED has different (and complementary) capabilities to that of programs like OSLO. The FRED software does ray traces and more but, beyond that, it is able to do the mechanical design work to make your optical creation actually function in the real world.
Homework Keys (to be posted on Canvas after the homework is due):
Another practice exam: Exam #2 2010
Image Analysis Software:
NASA’s Spotlight 8 and 16 Spotlight 8 (8-Bit and 16-Bit image analysis software). This software is meant for sequences of images but works just fine with a single image. It is actually flame analysis software but, again, will do some nice data analysis on any image.
I strongly suggest the 16-Bit software unless you are having problems of some funny sort.
Spotlight 8 Users Guide
Interactive Demos: Use your browser's back button to return to this page. Preliminary notes:
1. Do not simply run the application and move on. You should watch the application closely and study what happens. Change the parameters and watch for the results of the change. Read the short notes with most of the applets to help you get the most out of the time you spend working with that demonstration. Generally, you can use the mouse to control the programs.
2. You will need to use a computer that has a Java capable browser. Most of the computer labs on campus should work OK for this. If you have problems, please let me know about it.
3. There is an entire web site dedicated to optics animations and images. This site is called The Optics Project (TOP) and is very graphics intensive. There are modules on diffraction, polarization, you name it. I highly recommend this site! Note, access this site from a computer with a fast connection to the net.
Various optics physlets, many are unique and quite good.
Philliip Dukes Applets site.
Many applets by Fu-Kwun Hwang - really good!
- Here is a VERY cool demo of the principle of least time.
- Fu-Kwun Hwang has a Fermat's Principle too, you can choose the path and compare.
Reflection and Refraction demos:
- Java applet on refraction and reflection Simple ray and Snell's law demo.
- Java applet on refraction and reflection with Huygen's Principle.
- Interactive demo on refraction by Phillip Dukes at BYU.
- Another interactive demo on both reflection and refraction using Huygen's wavelets by Fu-Kwun Hwang.
- (Temporarily Dead Link) You can experiment with geometrical optics (reflection and refraction) by running the Italian LibLab applets. You can use the mouse to grab the incident ray and move it around.
- Fu-Kwun Hwang has made a thick lens demo too.
Thin Lens Demos:
- Interactive demo on thin lenses and the thin lens equation by Fu-Kwun Hwang, slightly modified by Phillip Dukes.
- Dr. Dukes has another that can be either a lens or a mirror as the user chooses.
- Fu-Kwun Hwang has a cool multipoint image demo for a thin lens which you can right mouse click to add or remove an additional thin lens.
- (Temporarily Dead Link) You can experiment with multiple lenses with this Italian LibLab group applet.
- Astronomical telescope - Java applet showing angular magnification.
- Thick lenses and aberrations.
Light Measurement and Sources:
- The Light Measurement Handbook (html version) or download the full 2.4MB pdf version.
- Specifically the photometry chapter.
- Good set of pages on photometry: http://www.cg.tuwien.ac.at/research/theses/matkovic/node5.html
- This UK site has the numbers to make a plot from the data (data every 1 nm): http://flatnet.phy.cam.ac.uk/glossary/convradphoto.htm
- This is a cool site, there is data (every 10 nm) but also comparisons, see "why is a candle flame yellow?" http://hyperphysics.phy-astr.gsu.edu/hbase/vision/bright.html
- The CCD University web site on the Apogee site is an excellent source of information about CCD detectors and their usage.
- Electric Dipole Radiation (by Falstad) Make sure you select the oscillating dipole from the top menu.
- Propagation of EM waves by Fu-Kwun Hwang.
- Double Slit Interference by Fu-Kwun Hwang.
- An excellent superposition of waves demo also by Hwang.
- Nice interference of light through a double slit. Has various views including angles and intensity.
- Single slit version of the previous link.
- A relativistic velocity, light cone, and twin paradox applet that is not for the timid, by Roberto B. Salgado.
- For the more advanced student, you can observe quantum mechanical scattering off of a barrier. Developed by John L. Richardson at Silicon Graphics, Inc.
Applications of Optics:
- View the spectra of various elements by John Talbot.
Cool, Fun and/or Useful Links:
All sorts of interesting links can be found at the Light Machinery web site. Topics range from glass to history to etalons to Java applets to you name it. They also have an online library of optics and a lot of neat optics calculations. These can be found at: http://www.lightmachinery.com/links.html
Spectroscopy net education page on detectors and other interesting stuff:
Ever wonder about the weird things you sometimes see in the sky? Here is a site devoted to Atmospheric Optics.
How to read a Vernier scale. (By Fu-Kwun Hwang.)
Lots of cool optics applets at MathTools.net
Lots of cool physics applets.
Lots of cool physics applets by Dr. Phillip Dukes.
