GPU-accelerated Multislice Electron Ptychography (MEP) reconstruction software · GPU 加速多切片电子叠层成像重构软件
The MEP Workstation reconstructs atomic-resolution phase images from 4D-STEM datasets using a full multislice forward model. It resolves thick specimens (>100 nm) beyond the reach of SSB / WDD / single-slice methods, delivers sub-picometer atomic-column statistics, and runs on a single GPU workstation or multi-GPU cluster.
| Reconstruction methods 重构算法 | Multislice ptychography (ePIE / rPIE / LSQML family), mixed-state probe, joint position refinement, depth sectioning |
|---|---|
| Specimen thickness 样品厚度 | >100 nm with atomic precision (multislice propagation) |
| Position precision 位置精度 | <1 pm atomic-column statistics (dose- and material-dependent) |
| Calibration 校准 | Probe aberrations (C1 / C3 / C5), scan distortion, detector response, specimen tilt — jointly refined; traceable calibration metadata in every output |
| Performance 性能 | ~100× vs CPU baselines; typical 256×256-scan dataset in minutes on one NVIDIA A100; near-linear multi-GPU scaling |
| Quantitative outputs 定量输出 | Phase maps, atomic positions, displacement / polarization vector fields, strain tensors, octahedral tilt, depth-resolved slices |
| Software license 软件授权 | Annual subscription per workstation / per cluster node — contact for quotation |
