The inverse scattering of the acoustic wave equation is an analytic method used to solve the inverse problem of determining coefficient terms in a hyperbolic partial differential equation. In the method, the Born approximation has been employed to linearize the inverse problem and an analytic solution has been obtained when the reference velocity is assumed to be constant. Because the assumption of small velocity disturbances in the Born approximation can hardly be satisfied in most cases, it is difficult to apply the solution of the constant reference velocity model to estimating the velocity disturbances. Considering a more realistic medium of a linear reference velocity, we first show the Green function and the expression of acoustic scatter waves, then obtain the analytic solution of the inverse scattering problem, resulting in a new procedure for inversion of the velocity disturbances. The inversion procedure must enjoy both high accuracy, due to satisfying the assumption of small velocity disturbances, and high computation speed by making it possible to employ the FFT algorithm.

声波方程的逆散射反演乃是求解双曲型偏微分方程系数项反问题的一种解析方法,一般利用Born近似把这一非线性反问题线性化,并给出了恒参考波速介质中反问题解的解析表达式.由于Born近似假定波速扰动为一级无穷小,因此,在大多数情况下,恒参考波速介质模型的反问题的解无法得以应用.本文研究介质参考波速沿某个方向线性变化时的声散射理论,导出了声波方程逆散射问题解的解析表达式,从而既可使Born近似的假定在大多数情况下能得以满足,又可利用快速Fourier变换快速实现介质波速扰动的反演成象.

In the previous paper, we have presented the acoustic inverse scattering theory for a linear reference velocity model, giving an analytic solution for the inverse scattering problem. Considering the practical applications of this method, we have introduced correspondent solutions for the following cases: 1. the two-and-one-half dimensional model with a point source, 2. high-frequency approximation of the solution. The extended studies shown in this paper make previously suggested methods of the inverse...

In the previous paper, we have presented the acoustic inverse scattering theory for a linear reference velocity model, giving an analytic solution for the inverse scattering problem. Considering the practical applications of this method, we have introduced correspondent solutions for the following cases: 1. the two-and-one-half dimensional model with a point source, 2. high-frequency approximation of the solution. The extended studies shown in this paper make previously suggested methods of the inverse scattering more applicable while the advantages tn the previous approach proposed by the authors, e.g. high computational speed due to employment of the FFT algorithm and more endurable to the assumption of Born approximation, are still hold.

我们在文献[1]里研究了介质参考波速沿某个方向线性变化时的三维声散射理论,导出了声波方程逆散射反演问题解的解析表达式.考虑到应用时的实际条件,本文根据上述反演方法导出2.5维模型的声波方程逆散射反演的波速扰动计算公式,给出该方法在“高频”近似条件下的波速扰动反演计算公式,从而使我们提出的“参考波速线性变化时的声波方程逆散射反演”理论更接近实际应用条件.本文给出的这些反演公式仍然具有原方法的优点,即不但可以使Born近似的假定在大多数情况下能得以满足,而且可以利用快速Fourier变换来快速实现介质波速扰动的反演成象.

A simple recording method of projection rainbow holograms with a diffused linear reference beam (DLR) is presented. When reconstructed, the image of slit is virtual and is much widened behind scene because of the DLR, so a entire virtual image of the scene can be viewed. That differs from reconstruction of general rainbow holograms.
