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 …

The k-function of Stavroudis describes a solution of the eikonal equation in a region of
constant refractive index. Given the k-function describing the optical field in one region of …

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 …

The apparent position, size, and shape of aerial objects viewed binocularly from water
change as a result of the refraction of light at the water surface. Earlier studies of the …

Optical systems are conventionally evaluated by ray-tracing techniques that extract
performance quantities such as aberration and spot size. Current optical analysis software …

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 …

In this work we use geometrical optics to obtain an exact analytical expression for the caustic
surface associated with the evolution of an aberrated wavefront in three-dimensional free …
