Acoustic levitation method is one of the techniques for container-less processing of a droplet, which is expected to be used for manufacturing of new materials and biotechnology. The purpose of this paper is to estimate thermal and mass transport phenomena in the vicinity of an acoustically levitated droplet. The present work is an experimental investigation of the concentration distribution around the levitated droplet using laser interferometry. The following results were obtained: In the sound field without levitating sample, interference fringes changed with the period of the sound wave. In the case of the hexane droplet, the change to the radial direction of the interference fringes were observed around the droplet.
