Ptychography　is　a　lensless,　wide-field,　diffraction　imaging　method　that　can　reconstruct　the　object　transmittance　function　and　the　probe　distribution　simultaneously.　Traditionally,　lateral　mechanical　movement　is　necessary　in　the　time-consuming　data　acquisition　process,　resulting　in　disability　to　investigate　dynamic　phenomena.　Single-shot　ptychography　is　therefore　proposed　which　divides　the　incident　light　into　multiple　tilted　sub-probes　through　a　beam　splitting　element,　e.g.,　pinhole　array　and　Dammann　grating,　meanwhile　the　diffraction　patterns　are　recorded　simultaneously　in　spatial　multiplexing　mode.　In　this　study,　we　propose　a　single-shot　ptychography　approach　using　a　phase-only　spatial　light　modulator.　In　order　to　realize　multi-angle　modulation,　four　different　grey　images　are　loaded　in　different　quadrants　of　the　modulator,　which　generates　a　specific　phase　delay.　Considering　the　inconsistent　wavefront　of　the　probe　beams,　multi-mode　ptychographic　algorithm　is　also　adopted　which　treats　probe　beams　differently.　The　proposed　method　is　expected　to　promote　single-shot　ptychography　for　piratical　applications.　©　2022　SPIE.
