Abstract

We proposed an optical method for imaging of a motion picture of sounds for selected frequency. We recorded three sounds of frequencies 39.5, 40.0, and 40.5 kHz with the frame rate of 100,000 fps by parallel phase-shifting digital holography and succeeded in imaging the sound for selected frequency.
