I am working on a project that involves statistical analysis of a laser speckle (reflection) of a nanopillared topology. My experimental setup consists of a He Ne laser, an opaque nanopillared sample and a CCD camera placed at a distance far from the sample to monitor the speckle pattern.

What I would like to do is to emulate my sample and look at the far field speckle intensity pattern using Rsoft (to emulate my measurements with the CCD camera). It looks like FullWave would give the intensity output in the far field however it is using the angular convention. Also, I am not sure if I can control the distance of the monitor from the sample structure itself. Long story short, I would appreciate a bit of insight if you have an experience about this particular usage of Rsoft.
