PyTIE

The following modules contain the base code for the TIE reconstruction, as well as display functions and the microscope class which is used for simulating LTEM images.

• TIE_reconstruct contains the final setup and TIE solver
• TIE_params is a class that contains the data and reconstruction parameters.
• microscopes is a class containing all microscope parameters as well as methods for simulating LTEM images.
• TIE_helper has loading and display functions
• colorwheel is for visualizing 2D vector images.
• longitudinal_deriv still has bugs, but calculates the intensity derivative through a full stack rather than through the central difference method.

The TIE reconstruction for the magnetic component of the electron phase shift has been shown to be quantitative when verified against simulated images. This is not the case for the electrostatic component, however. While the returned phase_e image will be qualitatively correct it is likely to be scaled incorrectly.
