Nonlinear acoustical imaging This book first introduced the theoretical foundation of nonlinear acoustics such as the basic equations of nonlinear acoustics followed by a statistical mechanics approach to nonlinear acoustics then a curvilinear spacetime approach to nonlinear acoustics then a gauge invariance approach to nonlinear acoustics and application of chaos theory to nonlinear acoustics. Various formats of nonlinear acoustical imaging are given such as B A nonlinear parameter acoustical imaging fractal imaging harmonics imaging nonclassical nonlinear acoustical imaging and modulation method in nonlinear acoustical imaging with their applications.
