OESD 4616/5616 Design Project Guidelines

Fall 2007

 

Typical outline of report:

 

  1. Selection and Specification: what is this device supposed to do.These should be the whats, not the hows.Think of it as the customer spec.Identify any specs that are uncertain, expected to be difficult, flexible, etc.
  2. Possible approaches and design selection.How could the problem be solved?Donít go too fast over this step Ė itís both the fun part and possibly the most important.Try to sketch out at least three designs (perhaps with rough paraxial layouts).Based on some analysis, select one for more in-depth design.
  3. Paraxial design.Using the method of your choice, work out the prescription (lens powers, distances, etc) to meet your specs (or not, if you find them impossible).If thereís an eyeball in your problem, include it.
  4. Gaussian design.Thicken the lenses.If you donít have specific lenses, pop open something like the Newport catalog (www.newport.com) or use some reasonable designs from our text.Include the stops, find pupils and windows.Calculate resolution and radiometry as appropriate.What specs to you expect to achieve?
  5. Aberration analysis and optimization, final report:Get your design into Zemax and see what performance you can achieve.Iíd recommend starting with paraxial lenses to match your design, then start inserting real glass.

 

Depending on your project, you may have extra pieces and perhaps not some of those above.

 

Grading rubric:

 

20points total.Reports should be all electronic (thatís the way the world works these days).If you donít have the right software, do neat drawings and scan them.

 

5: Presentation

         1: Interim results (turned in or not already)

         1: System-level view.Motivation of the problem to be solved and analysis of the design based on a clear understanding of the system and its needs.

         1: English and organization

         2: Clarity of analysis and figures.Your reviewer (e.g. boss, professor) should be able to understand your material easily.†† Take time to present your results clearly.

 

15: Technical content

         5: Level of effort.

         6: Proper use of design tools.You should strive to exercise as many of our tools as possible (you donít need to use multiple paraxial analysis tools, obviously), since thatís the point of the project.

         2: Creativity/originality.Even if you are working on a rather well-known problem, you should be able to propose novel approaches.If they are not reasonable, say why.

         2: Completeness and thoroughness of design. If you are not covering some important portion of your design, state explicitly that this is the case.That is, be clear on what parts of the problem you are solving and then do a good job on those parts.
