Thanks for the suggestion! I am very new to the optics side of this, but it's been a fun journey to learn. I was thinking about your idea of moving prism, maybe I can also see this as the moving cell (I know its motion between frames thanks to my simulations, but also I could model thermal fluctuations of the membrane), just to see as a first step if it changes anything. I'll definitely read more about it.
