| Research Abstract |
Examination about the ability of the water distribution measurement in very shallow soil to be performed by the acoustic imaging method using a sound wave and the laser Doppler vibrometer of high sensitivity was performed. From the experimental result using sand and culture soil, the relevance of propagation acoustic velocity and volume water content was confirmed. Moreover, from the experimental result using the container for roof planting, when the part where moisture content differs was very shallow, we confirmed that the visualization using the non-contact acoustic imaging method was possible.
