Title
Digital holographic vibrometry using stroboscopic illumination for full field, time resolved 4D imaging of nanometer vibrations
Author
Abstract
A stroboscopic digital holography setup using a high-power pulsed laser is presented. The setup can be used to visualize complicated vibrational patterns with nanometer amplitudes, ranging from quasi-static deformations to high frequency vibrations (1 Hz - 20 kHz). The technique provides both full field and time-resolved displacement information, in contrast to respectively single point LDV (laser doppler vibrometry) techniques and time-averaged holography. This is realized by recording single-shot holograms at multiple phases within the vibration period. The major challenge is to synchronize the laser pulses with the object frequency and the digital image acquisition. This is addressed by employing a microprocessor based timing sequence.
