Video-rate laser Doppler vibrometry by heterodyne holography
arXiv:1103.3592 · doi:10.1364/OL.36.001449
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.
