An experiment on image distortion correction in acoustical holography was conducted. Scanned acoustical holography was used for imaging objects through a 5.06cm thick curved aluminum slab. Image distortion due to the curved slab was corrected in the reconstruction stage using two holograms; one, the hologram of the object, and the other, the hologram of the distortion media. A relatively good result has been obtained by the present experiment.
