title: Optical beating of polychromatic light and its impact on time-resolved spectroscopy. Part I: Theory.
abstract: Optical beating of polychromatic light is reviewed and its potential impact on time-resolved spectroscopy is analyzed. In particular, the dependence of the quasi-random beating of thermal light on quantities including average power, spectral shape, and spectral width are reviewed.
