摘要
在普通物理的框架内对不同情况下夫琅禾费衍射光场的相位弯曲因子的形式进行了推导 ,并对其物理意义给出直观的说明 ;指出并讨论了该因子对光波传输过程的重要影响 ;从而纠正了光学教材中的一个常见误式 。
The form of phase curvature of Fraunhofer diffraction field and its concrete expressions in different conditions are derived in the frame of general physics, their physical meanings are explicitly explained. This phase factor has important effect on the process of wave propagation and imaging. Ignorance of it would cause some misinterpretations for image formation.
