[ALPS29-02] Ptychography Phase Retrieval via Threshold Truncation Alternating Direction Method of Multipliers Using High Harmonic Sources

*Shaobo FANG1,2, Xianming WU1,2 (1. Institute of Physics Chinese Academy of Sciences, 2. University of Chinese Academy of Science)

We introduce a closed-form ADMM algorithm for robust phase retrieval in Ptychography, utilizing a threshold truncation update method for penalty parameter adjustment. Our approach outperforms others, ensuring superior phase retrieval even with a 25% overlap rate.
