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 ...

Abstract: Multiplexed cavity ring-down spectroscopy (CRDS) is challenging to achieve as it requires a detection scheme able to retrieve many undistorted exponential decays simultaneously [1]. We ...

Abstract: Frequency comb technology has revolutionized many aspects of spectroscopic measurements, most recently exemplified by the introduction of multi-heterodyne spectroscopy, which is now ...

With the advancement of laser technology, ultrashort pulsating lasers give a new technological technique for highly precise spectroscopic measurement. To precisely monitor wavelengths, the optical ...

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, ...
