- tomopy.prep.phase.retrieve_phase(tomo, pixel_size=0.0001, dist=50, energy=20, alpha=0.001, pad=True, ncore=None, nchunk=None)[source]¶
Perform single-step phase retrieval from phase-contrast measurements [B10].
- Parameters:
tomo (ndarray) – 3D tomographic data.
pixel_size (float, optional) – Detector pixel size in cm.
dist (float, optional) – Propagation distance of the wavefront in cm.
energy (float, optional) – Energy of incident wave in keV.
alpha (float, optional) – Regularization parameter.
pad (bool, optional) – If True, extend the size of the projections by padding with zeros.
ncore (int, optional) – Number of cores that will be assigned to jobs.
nchunk (int, optional) – Chunk size for each core.
- Returns:
ndarray – Approximated 3D tomographic phase data.
