The article reports on a technique relative to interferometry devices that have made researchers to new means of measuring absolute distance with remarkable precision. This concept was brought forth by a team of researchers in the Netherlands which demonstrates distance precision which could be applied over thousands of kilometers. This technique has seen a development in both spectroscopy and metrology applications of the frequency-comb technique.
