Inverse Problems in Scattering

  1. Apr 22, 2013 #1
    Hi Guys,

    I am doing a bit of work with dynamic light scattering (DLS) data. It is one of the many areas of science where we encounter an inverse problem.

    The forward problem is: For a known sized particle, calculate its scattered spectrum (that is easy). The inverse problem is: from the scattered spectrum, calculate the size(s) of the partcile(s) that made the spectrum (that is hard).

    What I would like to know is how, given an experimental data set, do you invert that data set to get the original sample properties? I just read some books and they dont seem to go into the maths.

    Any help would be greatly appreciated. I am pretty good at MATLAB and would like to code my own inversion routines.

    Thanks

    Hi mate,

    thanks for the reply to my very old topic hah. I had a go at that cause the original CONTIN is too complicated for me to use. rILT seems to work but its very slow. I have been using other methods in the mean time.

    Thanks.
