A method for analyzing a diffusing sample comprises steps of: a) illuminating the sample with temporally coherent and wavelength-modulated incident light beam; b) producing a succession of interference signals with the diffuse light; c) combining each interference signal with a reference signal (Ref(t,tau<SUB>0</SUB>)) generating a time port; d) extracting the continuous component of each signal characteristic of the predetermined delay (tau<SUB>0</SUB>) derived form c); applying a nonlinear function on each of the continuous components of the signals characterizing the predetermined delay (tau<SUB>0</SUB>); and f) averaging each of the images, with the non-linear function, of the continuous components of the signals characterizing the predetermined delay (tau<SUB>0</SUB>). The invention is useful for observing organs of the human body. |
