Thank you @throbscottle, I am currently finishing part 2, which I will link here.
If after that you have more questions or ideas, please let me know.

Thanks for your comment!

Really good article, but I has hoping to find a Part 2 and a Part 3 at least! It would be nice to have something about how to read these encoders.

Yes this is also a common method of measuring displacement, again the magnetic encoders offer both incremental and absolute options.
The digital measurement systems we use and offer work in the same principle.

I've also been looking at magnetic encoders, these use a diametrically magnetised magnet and a DSP to determine the absolute rotation of a shaft. Output is typically PWM or digital.
