Ptycho! Image processing diffraction patterns

If you have a question about this talk, please contact Chris Richardson .

What is ptychography, and why should we be interested?

Imaging very small objects often involves using high energy or short wavelength beams, such as X-rays, which are difficult to focus. As a result, rather than images, experimenters often collect diffraction patterns, which record the intensity of the Fourier transform of the image.

The reconstruction of the image from the diffraction pattern is non-unique, because the phase information has been lost. However by combining multiple overlapping images in real space, it is possible to obtain a further constraint, which makes image reconstruction feasible.

This talk will introduce the topic, and show an example of some of the challenges of converting an existing Python script to C++ and running on a HPC .
