As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

Frequency comb spectroscopy exploits the generation of a light source whose spectrum comprises a series of discrete, evenly spaced optical frequencies—known collectively as a frequency comb—to carry ...

Absolute distance measurement techniques based on optical frequency combs have emerged as the gold standard for high-precision ranging over distances from micrometres to several kilometres. Optical ...
