Focal Shifts of Converging Spherical Waves with Non Uniform Amplitude I. Paraxial Light Beams
摘要
分析了傍轴非均匀振幅分布会聚球面波的焦移问题，给出了焦移量的解析表达式，并由此进一步揭示出：导致焦移的主要原因在于光束的内禀运动。
Abstract
In this paper the focal shifts of paraxial converging spherical waves with non uniform amplitude are analysed, and the analytical expression of the focal shifts is derived. Based on the theory of hydrodynamics model of optics (HMO), it is pointed out that the focal shifts are attributed to the intrinsic movements of the light beams.
