- 論文の詳細を見る
An optical method for measurement of sound fields using the Mach–Zehnder interferometer is described. In this study, we investigate the influence of diffracted light that passes through sound fields generated by radio frequency for measurement using the interferometer. The intensities of the diffracted light and the interference light are measured by a charge-coupled device (CCD). To compare the values acquired from the numerical estimation with those acquired from the measurement, we confirm the validity of the numerical estimation equation.
