Video-rate laser Doppler vibrometry by heterodyne holography

Published 18 Mar 2011 in physics.optics | (1103.3592v1)

Abstract: We report a demonstration video-rate heterodyne holography in off-axis configuration. Reconstruction and display of 1 Megapixel holograms is achieved at 24 frames per second, with a graphics processing unit. Our claims are validated with real-time screening of steady-state vibration amplitudes in a wide-field, non-contact vibrometry experiment.
