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, ...

The hyperspectral imager is based on the combination of a Michelson interferometer and a focal plane array detector (Fig. 1). A spectrum is determined for each pixel of the array. The spectrum ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...
