The oscillatory wall motion displacement versus pulse width and or pulse field strength were clearly detected for low damping as-grown garnet sample using dynamic bubble collapse method. We are continuing to investigate the origin of this oscillatory phenomenon and it had been speculated that the nondestructive sensing of bubble state during bubble collapsing is very important. The method in nondestructive sensing for X bubble is based on the principle of "Inplane Automotion". On the other hand, for σ bubble, on "Automotion II ". The optical microscope TV system enables the observer to distinguish between four kinds of bubble state (X+, X-, σ+, σ-) using only single combination of inplane dc field and inplane pulse field.
