Tried another type of the slider instead slit - results are great, I can adjust 3D effect (even it is not close to the aperture !)

Great images, Saul. Thanks for posting them.

Hoping you can add a bit of information to your setup. Is the "retarder" in your diagram a 1/4 wave, full wave or ?? plate. And is the rotatable filter /modulator a combination of ??? Do like that you've taken the time to model your setup. Regards, Pete

Nicely done. Good to see sharply focused polarized crystals.

Retarder for this photo was simple mica piece.
Rotatable filter/modulator - did not have right material on hand, so used small pieces of pol sheet and mica to make something similar to the HM modulator in order to match sliding slit in the insert.

Could be better with stacking ... :)

Another one. King Kong ?

33 photos, same setup, except modulator - got some "ND sheet" from China, so tried to improvise HM "thing" plus pol filter together on the rotatable insert above the objective.

Filters are temporary, just for testing, will make something better :) ...
Rotatable pol insert fits Nikon EPI illuminators, Microphots etc ( https://www.ebay.com/itm/323232270818 , 27mmx5.6mm) . It contains gears, when you are rotating one end, another rotates also.

Thanks Pete, it is correct - 1st photo is single shot, 2nd - stack of 33.
This is Nikon BD Plan 20x 0.4 , will try objective with higher NA
