The invention concerns an apparatus for parallel detection of the behaviour of mechanical micro-oscillators interacting with the sample (). The amplitude and the phase of resonance of micro-oscillators () are measured with optical means. The invention is characterised in that a source () is active during a fraction 1/n of the period (n being an integer) and of variable phase p/n of the period (p being an integer). Interferences are produced between light beams generated by reflection of incident light beams () and () on the micro-oscillators (). Periodically the micro-oscillators () are displaced by means. The value of the parameter p (p being an integer) is varied and N elementary measurements are integrated to obtain a measurement representing each of the values of p. The phase and amplitude of each micro-oscillator () are calculated on the basis of the representative data obtained for each value of p and this for a large number of accumulations. The invention is applicable in the field of nanotechnologies.
