DPCSignal2D#

class pyxem.signals.DPCSignal2D(*args, **kwargs)[source]#

Bases: Signal2D

Signal for processing differential phase contrast (DPC) acquired using scanning transmission electron microscopy (STEM).

The signal assumes the data is 3 dimensions, where the two signal dimensions are the probe positions, and the navigation dimension is the x and y disk shifts.

The first navigation index (s.inav[0]) is assumed to the be x-shift and the second navigation is the y-shift (s.inav[1]).
