The study concerns the determination of quadrature for the integral solutionof the paraxial wave equation. The difficulty in computation of the integral isassociated with the rapid change of the integrand phase. The developed quadraturetakes into account the fast oscillating character of the integrand. The presentedmethod is an alternative to the commonly used methods based on the use of theFourier transform. The determination of the quadrature is discussed on the exampleof the integral arisen in the theory of propagation and focusing on hard X-rayswaves. Due to the generality of the presented quadrature, it may also be applied toissues related to standard optics and acoustics.
