anyone have a sense of whether this will make a difference for small distances as seen in construction and small parts (less than car-sized) non-optical manufacturing? i feel like the precision available today, with handheld laser rules and what-not, are already cheap and accurate enough.
Traditional interferometry already achieves sub-nanometer precision. This is already many orders of magnitude more precise than most non-optical manufacturing processes, so I agree with your analysis!
