Abstract

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 Å to 3 μm peak to peak).
