magtomo.Experiment.Experiment

class Experiment(magnetization, rotations, pol=1j, order=1)

Bases: object

Defines an experimental setup for performing vector or orientation tomography.

Parameters:

magnetizationnp.ndarray

The magnetic configuration to calculate projections from.

rotationsnp.ndarray

Stack of rotation matrices describing the sample orientations that were measured; shaped (n, 3, 3).

polarray_like (optional)

Single polarization used for all projections, stack of polarizations matching the number of projections or stack of polarization pairs. Linear polarization represented using values from 0 to 180 (in degrees). Circular left and right polarization represented using complex ±1j.

orderint

The interpolation order (0-5) for performing rotations.
