Abstract
null null A multistep acoustic method is extended to suppress the more serious instability in the inverse process between the time-evolving pressure on the hologram plane and the time-wavenumber acceleration spectrum on the virtual source plane, and further stabilizes the reconstruction of the instantaneous vibration of an exciting planar structure. In the extended method, the solving equation relating the time-evolving pressure to the...
