Normalized autocorrelation functions for the tissue-mimicking non-absorbing phantoms with a variable reduced scattering coefficient ( ${{\mu }_s}^{\mathrm{\prime }}$ ) at increasing source-collector separations (columns) were estimated using variable integration times (rows). Autocorrelations for the variable ${{\mu }_s}^{\mathrm{\prime }}$ can be distinguished at long separations, provided the integration time is 5-10 msec.
