Limitations for Frequency-based Absolute Length Measurements

  • Michael Danos


The advent of the laser has provided for a quantum jump in the accuracy available for the definition of length and for the stability and accuracy of its measurement. In particular, it has allowed the replacement of the independent unit, “the length” by the wavelength of a suitable optical frequency. This frequency, by means of a chain of frequency multipliers, could be related to the time unit, the second, which is by far the most accurate and reproducible of the various physical quantities.
