LASER INTERFEROMETRIC MEASUREMENTS OF VERY SMALL VIBRATION AMPLITUDES OF THE ORDER OF ANGSTROMS AND ITS APPLICATIONS

The measurement of vibration amplitudes ranging from several angstroms to several hundred angstroms is a subject of interest, because this is the range of acoustic emission signals, and calibration of transducers at frequencies, for example, higher than 50 kHz also needs the amplitudes within this range. Two laser
