Imaging through scattering media with the double aperture set-up

To obtain the image of an object obscured by moving scattering media, a set-up involving a lens with double aperture is employed. The condition for the minimum speed of the scattering media is first derived, the evaluation of which using the set-up parameters yields 0.038 km/h. An improved reconstructed image is then confirmed in the experiment. Advantages of the technique include the relief of the need, respectively, for a local reference beam and a mechanically very stable set-up.
