Abstract: The comb function is defined as equidistantly spaced impulses (i.e., an impulse train); it is well known that its Fourier transform also provides a comb function, and is used for a proof of ...

Fourier transform spectroscopy is regularly used to measure complex broadband optical absorption or emission from molecules. In these measurements, fast and sensitive acquisition of accurate and ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...
