Abstract
Principles of an alternative approach to the ray theory and paraxial r ay approximation (PRA) theory are discussed. Invariant equations for t he ray, the eikonal equation and basic equations of the PRA-theory are derived on the basis of Riemannian geometry. Paraxial rays and paraxi al time field equations in general curvilinear coordinates are shown a s an example of application.
