| Abstract: | 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. |
