Frequency comb takes a measure of distance
Physics World
Physicists have unveiled a new method for measuring distance based on an optical frequency comb. The main benefit of the technique, which involves passing the light from an optical comb through a Michelson interferometer and analyzing the resulting interference patterns, is that it allows distances to be measured accurately without already knowing the value to within half a wavelength of the light used.
