Abstract
By using double-exposed holographic interferometry, the distribution of sound pr essure in the acoustic levitation field is analyzed. The holograms under differe nt conditions are obtained and compared with each other. It is shown that the me asured holograms are consistent with the theoretical ones, and the intensity dis tributions along their central axis are identical. Compared with other methods, double-exposed holographic interferometry has the merits of non-contact, non-int rusive and whole-field measurement; and it provides a more convenient and more i ntuitionistic approach to realize acoustic field and guarantees the optimization of acoustic levitation system.
