摘要: Publisher Summary This chapter discusses the theory and applications of complex rays. Complex rays are solutions ray equations traditional geometrical optics but correspond to extremals in six-dimensional space. The basic for ordinary optics, properties rays, selection rules associated with them. These results follow from application standard asymptotic methods, such as stationary phase saddle-point Kirchhoff wave propagation. presents examples trajectories different optical physical problems a analysis Gaussian beam also certain distinctive aspects including nonlocality applicability. considerations serve give some measure significance ray.
