本文报道了用低相干干涉法在光频域中被动测量含时绿色函数。在声学和地震学以前的研究的启发下，我们展示了如何宽带和非相干波场的相关性可以直接产生复杂介质的散射体之间的绿色函数。检索的弹道和多次散射分量的绿色的功能。这种方法为复杂散射介质中的光学成像和表征开辟了重要的前景。
We report on the passive measurement of time-dependent Green's functions in the optical frequency domain 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. Both the ballistic and multiple scattering components of the Green's function are retrieved. This approach opens important perspectives for optical imaging and characterization in complex scattering media.
