Abstract
Many problems associated with acoustical holography are caused by the large difference between the wavelength of the recording acoustic waves and the wavelength of the reconstructing light waves. These problems can be partially compensated for by reducing the size of the acoustical hologram. It is demonstrated that there is a value of the reduction ratio that produces a maximum image size with small aberrations.
