ABSTRACT:
The inventive method for opto-acoustical imagery of an image object consists in a) generating an incident optical wave and a reference optical wave coherent therewith, b) oscillating the image object area at an acoustic frequency, c) sending the incident wave to said image object, thereby generating a diffused signal wave, d) sending at least one part of said diffused signal wave to a detection device, e) sending the reference optical wave to the detection device avoiding the image object, thereby generating an interferogram I (r, t), f) extracting digital information from said interferogram I (r, t), and in g) obtaining co-ordinates from one measurement point of the image object associated to said digital information.
