A two-point phase recovering with spherical wave reference
R. G. Novikov, V. N. Sivkin
We consider a reference wave, a radiation solution, and the sum of these solutions (total solution) for the Helmholtz equation in an exterior region. We give two-point formulas for…

A two-point phase recovering from holographic data on a single plane
Roman Novikov, Vladimir Sivkin
We consider a plane wave, a radiation solution, and the sum of these solutions (total solution) for the Helmholtz equation in an exterior region in . In th…
