Paper Abstract

A non contact all-optical method for surface photoacoustic is described. The surface acoustic waves were excited employing a ArF excimer laser in the 10 µm thin polyimide film and detected with a Michelson interferometer using 633 nm HeNe laser due to an active stabilization for interferometer a surface displacement of 0.2 A. could be detected used for the purpose of discriminating between normal and maligned tissue. The acoustic waves propagate several millimeters in the sample differentiating maligned areas from normal breast tissue samples which having different acoustic impedance.
