Proceedings Paper • Open AccessTheory of optical imaging in the wave approach
The imaging theory fully based on the wave approach is proposed. In the paraxial region an optical system can be divided into two independent parts. The imaging by the first part consisting of focusing elements is similar to the geometrical imaging. The consideration of the wave propagation through a second part being a set of distorters is sufficient to analyze the diffraction phenomenon occuring in the optical system. The outline of the theory followed by a few practical examples are given.
