Reconstruction of bi-dimensional images in Fourier-Transform Acousto-Optic Imaging

Résumé

We present a new method to perform acousto-optic imaging based on a spatio-temporal structuration of long-duration acoustic plane waves. This approach is particularly relevant when using detectors with long integration time. We show how it is possible to reconstruct an image by measuring its two-dimensional Fourier components. A proof of concept is presented using a photorefractive detection scheme, demonstrating equal performances to direct imaging. The overall acquisition time is compatible with medical monitoring applications.
