Abstract
An acoustic hologram is constructed using a sound wave (20 kHz), scanning the acoustic fields by a microphone, and lighting a lamp by amplified electrical signals from the microphone. The original image is reconstructed to illuminate the sound wave hologram of reduced size by the laser light (6328 Å) and observed by a microscope.
