Author here. Lots of questions about precision --- in the article I calculated 0.6mm as the standard deviation of 200ms worth of phase measurements (n=124) while the slide wasn't moving.
I'd love to hear any advice/ideas re:
- approaches for figuring out what's currently limiting the accuracy (i.e., noise sources)
- the relative merits of averaging in time vs phase domain

- how to improve the analog frontend (See my collaborator Mitko's github repo for the hardware schematics: https://github.com/MitkoDyakov/Calipatron/blob/main/Hardware...)
