Brief

The article proposes using an optical circulator for the frequency-based remote comparison of linear measures kept in different laboratories.

Summary

This article proposes a new method for remotely comparing linear measures using an optical circulator to perform frequency measurements of length, which allows for calibration without physically transporting standards and can be tied to standard frequencies transmitted over communication channels. This method offers a sensitivity comparable to optical interference methods and potentially higher accuracy when synchronized with standard frequencies.
