Abstract

We propose photon-density-wave fluctuation correlation spectroscopy as a method to study the macroscopic dynamics of tissue optical properties. Phantom measurements have shown that our frequency-domain instrument is appropriate to explore intensity, modulation and phase fluctuations in the frequency band from 0 to 125 Hz. Preliminary in vivo studies have revealed a reach optical dynamics in human tissues.
