How to design a larger aperture DOE？

[BecIcan]

Hi singer-yang,
Excellent work, thanks for the open source. I am a PhD student at the University of Chinese Academy of Sciences (UCAS), and my research focuses on end-to-end optimization of DOE for large aperture and large field of view studies. I would like to use your framework for optimization, but I see that the DOE seems to be limited in terms of aperture, is it possible to design a large aperture DOE(e.g 8cm) using the framework? Looking forward to your reply!
Best regards. Wish you a nice weekend in advance.
