WebTemporal coherence . is the correlation of the electric fields at the same position, but at two different times: . And . mutual coherence . is the correlation of the electric fields at different positions and also at different times: . Mutual coherence contains both spatial and temporal coherence ... Webcoherence time (or length) “increased”, or that dispersion changes the coherence of light. In fact, the autocorrelation function for each field of the interferometer is unchanged. It is only their cross-correlation that is sensitive to unbalanced dispersion. Perhaps a more accurate description is to say that, in the presence of

WebNov 21, 2024 · The auto-correlation function, which is the same as coherence function, is the Fourier Transform of the Power Spectral Density of the source. For short coherence, a wide band source, I.e white light source is needed. The greater the bandwidth the shorter coherence length, but coherence function is maximum at zero time shift.
