Video-rate laser Doppler vibrometry by heterodyne holography.

Benjamin Samson1, Frédéric Verpillat, Michel Gross, Michael Atlan.   

Abstract

We report a demonstration video-rate heterodyne holography in off-axis configuration. Reconstruction and display of a one megapixel hologram 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, noncontact vibrometry experiment.
