First of all I know what the acronym stands for, but I assume I am not alone when it comes to the complexities of calculating MPE. Could someone give a fairly laments termed rundown of the process? I am a physics fanatic, but when it comes to some more advanced stuff I am a bit rough (its been a few years since my last formal class).
Also when it comes to diffraction gratings and such, how can one calculate the MPE? or is it more of a rule that diffraction gratings should never be directed towards the audience. Please keep in mind that I know any type of audience scanning is illegal in the US, however, I am merely wondering for the sake of my own knowledge.
Thanks,
Max
