MasterPatternBackend

class de_ebsd.diffraction.MasterPatternBackend

Bases: ABC

Interface every master-pattern intensity backend implements.

A backend receives a batch of unit incident-beam directions (Cartesian crystal frame) and returns one backscatter intensity per direction. The simulator handles gridding, chunking, and assembly into the Lambert maps.

Methods

intensities	Intensities (K,) for unit directions (K, 3).
prepare	Build and cache per-simulation tensors on the target device.

Attributes

name
uses_depth_profile	whether this backend consumes a Monte Carlo exit-depth profile; the simulator builds a native one (EMsoft-free) when the user supplies none.

abstractmethod intensities(directions)

Intensities (K,) for unit directions (K, 3). Called after prepare.

abstractmethod prepare(inputs)

Build and cache per-simulation tensors on the target device.

uses_depth_profile = False

whether this backend consumes a Monte Carlo exit-depth profile; the simulator builds a native one (EMsoft-free) when the user supplies none.
