The vector approach introduced in an early paper for modeling mirror-scanning devices [Y.
Li, Appl. Opt. 34, 6417 (1995)] provides the basis of a rigorous study of the scan field …

We study the formation of caustic surfaces formed in both convex-plano and plano-convex
aspheric lenses by considering a plane wave incident on the lens along the optical axis …

We study the formation of the caustic surfaces formed in both convex-plane and plano-
convex spherical lenses by considering a plane wave incident on the lens along the optical …

We study the formation of caustic surfaces formed in both convex-plano and plano-convex
conic lenses by considering a plane wave incident on the lens along the optical axis. By …

In this work we use the geometrical point of view of the Ronchi test and the caustic-touching
theorem to describe the structure of the ronchigrams for a parabolical mirror when the point …

The aim of this work is threefold: first we obtain analytical expressions for the wavefront train
and the caustic associated with the refraction of a plane wavefront by an axicon lens, second …

The main contribution of the present work is to use the probability density of an Airy beam to
identify its maxima with the family of caustics associated with the wavefronts determined by …

We study the formation of caustic surfaces produced by a concave conic mirror considering
a point source placed at arbitrary position along the optical axis. Using the caustic formula …

In this work we assume that we have two given optical media with constant refraction
indexes, which are separated by an arbitrary refracting surface. In one of the optical media …

We use geometrical optics and the caustic-touching theorem to study, in an exact way, the
change in the topology of the image of an object obtained by reflections on an arbitrary …
