About the approximation of a field of an extended source by a sphere wave in the far illumination region
On the base of a coherent emitting straight segment, the problem of approximate description of the field of an extended source in the far illumination region is considered. It is shown that in regions close to the directions of intensity maximums the source field can be approximated by mean of spher...
