What is Optimal Diversity in Phase Retrieval about?
The document discusses the assessment of wavefront-sensing performance in phase-diverse phase retrieval, focusing on the effects of varying aberration spatial frequency and diversity defocus. It presents analytical predictions for optimal diversity values that enhance phase-retrieval estimation performance and identifies a maximum diversity defocus beyond which performance declines. The findings are consistent with the Cramér–Rao lower bound and Talbot imaging phenomena, providing insights into the design
