Simultaneous 3D location and size measurement of spherical bubbles using cylindrical interferometric out-of-focus imaging

Abstract : A cylindrical interferometric out-of-focus imaging set-up is presented for the characterization of spherical bubbles. The design of the set-up is realized using transfer matrix based models. The simultaneous three-dimensional (3D) location and size measurement of bubbles is demonstrated using fast Fourier transform algorithms. Experimental results are in very good agreement with theoretical predictions.
