A fiber light engine design with pocus adjustment (Invited Paper)

13 April 2026 • 10:50 - 11:20 CEST | Luxembourg/Salon 2 (Niveau/Level 0)

Abstract

No, this is not a typo. Pocus is a third order effect such as the Seidel aberrations. In contrast to those, pocus does not affect the image but changes the angles of incidence for every image location.
In our paper, we will modify the pocus of an image to solve an illumination design problem. The purpose is to modify the intensity distribution at the exit of a fiber or light guide within the range supported by the numerical aperture of the fiber. There is a wide variety of applications conceivable in the technical and medical fields.
