Paper Abstract

We describe here the detailed signal processing technique that we have introduced to detect ultrasonic speckle modulation using a CCD array. We show that this new approach leads to a better signal to noise ratio than the single detector one not only because all the speckle grains signals are used but also because averaging over a few 104 grains smoothes this random signal. Finally a few examples of signal generated by locally absorbing volume immersed in real biological tissues are given.
