comment How to measure the slit size from given image using mathematica?
Although the answers linked by @Karsten can also answer this question, I think this one's still distinct because it doesn't focus on the variation in slit width. This simplification makes it possible to get results with a simpler approach, which I point out in my answer. It would also apply to the other question, but would require more work to characterize the variations.

comment Integral t^2/(1+t^4) using residues theorem
You didn't specify the integration path. More importantly, this is a site for the software Mathematica, so to get an answer you'll need to show the code you have tried.

comment Computation of a Fresnel Diffraction pattern with Discrete Hankel Transform
This should be a comment with the answer you're referring to. The question doesn't say what post you mean. You can try to make this into an independent question by stating the problem clearly.

comment Difficulties with Importing PDFs in Mathematica
@Masi It works fine for me. I can't say anything about your OS. Make sure you have a recent version of ghostscript.
