Real time measurement of very small transverse displacements of diffuse objects by random moiré, 2: Experiments.
We first briefly describe a realization of the random moiré displacement transducer (Part 1 of this paper). The principal problems arising in practical measurements, namely, stability and noise, are then discussed. Finally, results of several vibration measurements are presented, with various waveforms and amplitudes (2 A to 3 microm peak to peak).
