            Abstract : 
We report on the passive measurement of time-dependent Green´s functions in optics with low-coherence interferometry. Inspired by previous studies in acoustics and seismology, we show how the correlations of a broadband and incoherent wave-field can directly yield the Green´s functions between scatterers of a complex medium.
