Quantitative measurements were achieved using different techniques associated with an imaging bundle fiber: (1) the double-reference beam holography method with cw or pulsed laser, (2) TV-holography with cw laser, (3) shearography with cw or pulsed laser, and (4) real-time holographic interferometry with a repetitive frequency-doubled YAG laser working at 25 Hz. Deformations of a loaded aluminum plate or a rubber membrane were calculated using image processings.
