Abstract:

In the cavity survey, we already have the technology for observing the existence and an approximate shape. Detailed information is needed to know the volume and whole shape of the cavities. However, it’s impossible of only 6cm in diameter. Therefore, the small point cloud observation device has been newly developed.
