摘要

在相干发射直线段的基础上，考虑了在远光照区域近似描述扩展光源场的问题。结果表明，在接近强度最大值方向的区域，源场可以用球面波的平均值来近似。并找到了相应区域的球性条件。还讨论了用平面波近似扩展源场的问题。通过对球面波的下一次近似，找到了用平面波近似扩展源场的条件。

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 sphere waves. The sphericity condition in corresponding region is found. The problem of approximation of an extended source field by means of a plane wave is also discusses. As a result of a next approximation of a spherical wave, the condition for the approximation of a field of extended source by means of a plane wave was found.
