We have implemented an exact ray trace through a plano-freeform surface for an incident
plane wavefront. We obtain two caustic surfaces and provide the critical points related to the …

We study the formation of images in a reflective sphere in three configurations using caustics
on the field of light rays. The optical wavefront emerging from a source point reaching a …

Computing locations and extent of images, except in the most trivial configurations or special
cases, is a complex task. Even rays emanating from a point source and passing through an …

A method to design a dialyte based on the caustic surfaces is presented, with correction at
the third-order spherical aberration. We predefined, a priori, the value for the back focal …

We study the formation of caustic surfaces produced by convex conic lenses, considering a
linear set of point sources displayed on a plane, this linear array is placed at arbitrary …
