### Zernike Calculations in Julia

Recently, a fast and robust method of calculation of the Zernike polynomials and their derivatives in Cartesian coordinates was published. It was really easy to translate the published pseudo-code in Julia. The implementation appeared to be indeed very fast, so I could not resist to play with some visualisations.

### Running Julia in WSL

Windows 10 offers a friendly way to instal and use Linux system (the so-called WSL). Quite unexpectedly, Julia runs faster in WSL. You can check it yourself following the steps in this short tutorial.

### Using forestry to manage my site

forestry.io provides a user-friendly web-interface to manage static web sites. The question is whether this is easier than creating and editing the pages from IDE?

### Frequency Identification With TFFT

In Mathematica documentation devoted to Fourier command, I’ve stumbled upon a curious example of the frequency identification from a noisy data. The most interesting part was that the frequency (or the period) was found with high accuracy. And this was done by just changing the parameters of Fourier command!

# Projects

MADEin4 stands for Metrology Advances for Digitized ECS industry 4.0, an ECSEL JU project focussing on the productivity enhancement in “Industry 4.0”. Glasses for AI Our part in the project is to increase the throughput of the quality control lines.

#### Phase retrieval for high NA cases

For high values of numerical apertures (think microscopes), the standard phase retrieval methods are not reliable. In this project, we work on adjusting and expanding the low-NA algorithms to the high values of NA.

# Fun with …

It would be too boring to have only professional activities in life. In my free time, I enjoy aikido, listening and (learning) playing music, reading, solving geometrical puzzles, and just spending time with my family and friends. Sometime I share with them unexpectedly beautiful things I stumble upon in my research, which I also publish here.
