Abstract:
A method is proposed to calculate the area change and the volume displacement of a deformed membrane from the measurement of its displacement amplitude on a regular grid of observation points. The method is demonstrated on a circular latex membrane deformed by air pressure. The displacement data are obtained by phase shift moire interferometry. Area changes down to 0.5% and volume changes down to 16.1 mm(3) are measured, and error flags are determined.
