In order to simulate WFE in my design, I’ve added a Zernike Fringe Phase surface in the exit pupil. I then generate the desired amount of error through optimization of a merit function with ZERN operand (ZERN(-5)) and I’ve defined the 37 zernike parameters of my surface as variables.
It works but it generates almost exactly the same WFE (same WFE amplitude which is expected but also same wavefront shape) at each run of the optimization (I reset all parameters to zero before a new run).
What could I do to end up with a different wavefront shape?
