I can upload my project - how I made optical encoder system with about
600 ppr, with disc diameter of 50 mm. Increasing the diameter, you can
proportionally increase number of ppr.
This project is easy, with standard components. You only need to
purchase optical disk, (positive film).
If anyone is interested, sign up me.
