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