  • Have you tried a checkboard of holes and mirrors instead of black and white?  The belt and pulleys was a nice trick. You should check with a high speed camera if dots are synched. Perhaps larger pulleys would give you more resolution.  Try synching a single dot at a time, hiding the others on the sensor and projector discs. I think that would help debugging the issues
