I ran the Fresnel diffraction example code provided in the RayPier documentation (https://raypier-optics.readthedocs.io/en/latest/examples/fresnel_diffraction_example.html) on Python 3.8, but I could …

Hi,
I am working on indexing of spot and Kikuchi patterns in transmission mode in a SEM using the technique called on-axis Transmission Kikuchi Diffraction (TKD). Given the low acceleration voltage…

Hello,
I am acquiring raw diffraction patterns in a .tif format and I wanted to post-process and index these with Kikuchipy.
However, it seems like Kikuchipy does not support .tif files.
Could yo…

I'm dealing with a system composed of particles comfined in a circle and particles have arranged themselves into a triangular lattice. But I find that, the diffraction pattern is related to the box. S…

Currently all tests begin their work from the original object to reconstruct and then use the function diffractionPattern to create, well, the diffraction pattern :). Normally the input is a diffracti…

**Describe the bug**
When calculating a diffraction pattern, I expect the symmetry of the diffraction to reflect that of the particle positions. However, if the box has edges of different lengths, th…

During the ptypy workshop we came up with the idea that ptypy should give a final report at the end of a reconstruction. Some metrics that are worth knowing about the reconstruction:
- what was the…

I thought I could use the parameter `resolution` in Ptypy to implement the super-resolution approach, but it does not work as expected. Images of the results below.
The pixel size of the object and p…

Procedure: Compute a diffraction pattern for a circular aperature.
Usage: diffraction **radius** [**n-points**]

Now that freud can give us a diffraction pattern, lets work on creating a tool that can generate the structure factor from the raw data of these patterns.
