Auto-correlation is the correlation of a signal with itself (single waveform). It provides a measure of the similarity between observations as a function of the time lag between them. It is an ...

"The photonic architecture we developed enables real-time calculation of the cross-correlation function of two input signals for about 200 values of relative delay simultaneously," said Guillet de ...

This light‐travel time delay provides a characteristic radius of the region producing the emission lines. The cross‐correlation function (CCF) is the standard tool used to measure the time lag between ...
