ktc_tools

Python library for simulating TEM diffraction from FIB-milled phase gratings. Developed in the McMorran Lab at the University of Oregon.

Installation

Clone the repo and install as an editable package:

git clone https://github.com/McMorranLab/ktc_tools.git
pip install -e ktc_tools/

Editable install means changes to the source files are immediately active — no reinstall needed.

Usage

from ktc_tools import grating_generation as ggen
from ktc_tools import fourier_diffraction as fd

Modules

• grating_generation — constructs 1D and 2D grating transmission functions from parameterised depth profiles
• fourier_diffraction — computes single-grating diffraction patterns and efficiency spectra via Fourier optics
• corrected_holography — holographic reconstruction utilities
• streams — generates FIB streamfiles for grating milling patterns
