tike 0.0.0

No project description provided

Tike is a toolbox for tomographic reconstruction of 3D objects from ptychography data.

The aim of Tike is to provide fast and accurate implementations of a wide variety of reconstruction algorithms, and to provide a common platform for the synchrotron research community.

Current Features (March 2021)

Scan

• Lissajous and 2D spiral trajectories

• hexagonal and rectangular grids

Ptychography

• FFT-based operator with linear position interpolation

• single-energy

• multiple probes per diffraction pattern (multi-mode probes)

• probe variation correction (eigen probes)

• one shared (multi-modal) probe per angular view

• multi-GPU conjugate-gradient descent solver

• multi-GPU least-squares + gradient descent solver

Laminography

• USFFT-based operator for cubic field-of-view

• single tilt angle

• multi-GPU conjugate-gradient descent solver

Alignment

• Lanczos-based rotation and flow operators

• Cross-correlation rigid alignment solver
