AI中文摘要：
我们考虑外域中亥姆霍兹方程的参考波（辐射解）与这些解的和（总解）。针对球面参考波的情况，我们给出从总解强度恢复辐射解近似相位的两点公式，表明这些公式可用于从单个平面的全息数据恢复近似相位，延续了此前平面波参考的相关研究。
英文摘要：
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 approximate phase recovering of the radiation solution from the intensity of the total solution for the case of spherical reference wave. We show that these formulas can be used, in particular, for approximate phase recovering from holographic data on a single plane. By these formulas, we continue previous studies with plane wave reference.
