METHOD FOR ANALYSING A DIFFUSING SAMPLE BY TIME RESOLUTION MEASUREMENT

摘要

The invention concerns a method for analysing a diffusing sample comprising steps which consist in: a) illuminating the sample with a 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 >0<)) generating a time port; d) extracting the continuous component of each signal characteristic of the predetermined delay ( tau >0<) derived form c); applying a non-linear function on each of the continuous components of the signals characterising the predetermined delay ( tau >0<); and f) averaging each of the images, with said non-linear function, of the continuous components of the signals characterising the predetermined delay ( tau >0<). The invention is useful for observing organs of the human body.
