Diffuse holographic interferometric observations have been applied to generation and propagation of spherical shock wave in PMMA block and of blast waves in.air. The former case was made by means of laser beam focusing in PMMA and the later case was created by explosion of microexplosives. A curved film holder on which 70 mm wide and 300 mm long holo film was tightly fixed, was used so as to construct clearer holographic images and to broaden effective view angles when the film is reconstructed. The three-dimensionality of the images was well demonstrated.
