Can you translate/tilt a mirror in poppy.OpticalSystem Class?

[gkstmdwn]

I want to see how translating/tilting a mirror affects the PSF/WFE in an Optical System with more than 1 mirrors

Yes, in general these can be modeled, though the details of how best to do so depends on the specific optical element class being used. Many of the optical element classes support translation and rotation via setting attributes optic.shift_x or .shift_y or .rotation (for rotation around the optical axis). For tilts, you can use the TiltOpticalPathDifference class, or the TipTiltStage class to represent tilting some arbitrary optic (see https://poppy-optics.readthedocs.io/en/latest/available_optics.html#Tip-Tilt-Stage)
