Abstract
The properties of a solid specimen depend on its elastic property and microstructures, which are not only in nano size but also in micro-sized scale. Impulse acoustic microscope is a technology, employing a focused ultrasound probe beam in immersion to penetrate into a solid specimen, and to detect the internal micro-sized structure by acoustic imaging for a solid bulk material. Acoustic lens produces such a probe beam into a specimen and receives response radiations reflected from the specimen. The characters of an acoustic lens determine the precision and quality of acoustical imaging; and the relevant controlling techniques are also important peripheral elements for the system. But it is ignored or has not raised attention that the acoustic interaction behavior between the focused ultrasound probe beam and an internal micro-sized structure in a bulk — diffraction, scatter phenomena — usually also presents an inevitable impact on acoustic images. In this paper, the authors try to introduce these principles to demonstrate that these factors are the fundamental keys, to promote the performance of Impulse Scanning Acoustic Microscopy.
