Time-averaged shadow-moiré method for studying vibrations.
A time-averaged shadow-moiré method is presented which permits the determination of the amplitude distribution of the deflection of a plate in steady state vibration. No stroboscope is required, and the recording is done statically. The method is less sensitive than holographic methods and is therefore suitable for studying relatively large amplitudes.
