<title>Peculiarities of interferometer temporal signal in partially coherent light of multiple sources</title>

Abstract

The presence of two or more distinct local maxima in the power spectrum of radiation results under certain conditions in appearance of peculiarities in interferometer temporal signal. These peculiarities are manifested as a single coherent trough (minimum) in envelope of interferometer signal and as a rc-jump of phase of this signal in the point of envelope's trough.The coherent trough can be used as a measuring signal in the partial coherence interferometry. The conditions for observation of single coherence trough in envelope of interferometer temporal signal are discussed.
