i am desing a intefreomere by modulating the phase of the incident light so it splits the beam into two. I could design the phase mask using grid phase surface in zemax with sequential model. since in sequential mode no detector view is available i could not see any fringe formation. Instead, i could see only two overlaped beams.
Is their any possibility to get a detector square view in sequential mode? or
How to import grid phase to non sequentila mode?
