Tike

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
