We develop a scattering theory for perturbations of powers of the Laplacian on asymptotically Euclidean manifolds. The (absolute) scattering matrix is shown to be a Fourier integral operator associated to the geodesic flow at time $\pi $ on the boundary. Furthermore, it is shown that on ${{\mathbb{R}}^{n}}$ the asymptotics of certain short-range perturbations of ${{\Delta }^{k}}$ can be recovered from the scattering matrix at a finite number of energies.
