Scope of non-paraxyity of beams in the formation of images by spherical mirror

Abstract

The classical geometric optics manuals indicate that paraxial homocentric beams, when refracted on spherical surfaces, can form clear images of small spherical elements being placed perpendicularly to the optical axis. In particular, a spherical concave mirror when placing an object – a luminous point – in its focus should display it at infinity, that is, forming a plane-parallel beam. In reality, the notion of paraxiality is relatively arbitrary and any rays reflected by the mirror are more or less parallel to the optical axis. The report presents the results of an analysis of the light field formation after the reflection of light from a spherical mirror when a point source is placed in focus. Scientific supervices: prof.
