Hello,

I am trying to simulate a system that uses a Acousto-optic deflector to introduce an angle so that we can scan the beam around a few mm range. 

I am using a diffraction grating to simulate this in Optics studio but when I use POP to analyze the beam, it seems to always display in reference to the beam center, regardless of the actual displacement caused by the beam angle. 

Is there some way to have POP show the actual location of the beam? Maybe it is something simple I am missing.

I attached a picture in case my question was not clear. the orange highlighted surface is the surface that I am looking for the displacement at. 

Thanks for your help and sorry if this is a silly question!

Matt
