• Experiments on acoustical holographic interferometry were performed by scanned acoustical holography with 3 MHz sound waves. Interferometric imaging of tilted objects was performed and clear fringes corresponding to the height difference in the objects were observed in double-exposure interferometry and in two-hologram interferometry. Capability of acoustical interferometry to measure inclination of flaws in massive material has been shown in the double-exposure interferometry experiment. Two-frequency interferometry experiments were also performed and contour lines were superimposed on the reconstructed images. Good agreement between calculated and measured height differences in the object was obtained.
