Spherical wedge billiard: from chaos to fractals and Talbot carpets
Tomáš Tyc, Darek Cidlinský
We introduce the spherical wedge billiard, a dynamical system consisting of a particle moving along a geodesic on a closed non-Euclidean surface of a spherical wedge. We derive the…
Memory effect assisted imaging through multimode optical fibres
Shuhui Li, Simon A. R. Horsley, Tomas Tyc +2
When light propagates through opaque material, the spatial information it holds becomes scrambled, but not necessarily lost. Two classes of techniques have emerged to recover this…
Dr TIM: Ray-tracer TIM, with additional specialist scientific capabilities
Stephen Oxburgh, Tomas Tyc, Johannes Courtial
We describe several extensions to TIM, a raytracing program for ray-optics research. These include relativistic raytracing; simulation of the external appearance of Eaton lenses, L…
Multi-focal spherical media and geodesic lenses in geometrical optics
Martin Sarbort, Tomas Tyc
This paper presents a general approach to designing the isotropic spherical media with complex spatial structure that provide different types of imaging for different light rays. I…
Spectra of absolute instruments from the WKB approximation
Tomas Tyc
We calculate frequency spectra of absolute optical instruments using the WKB approximation. The resulting eigenfrequencies approximate the actual values very accurately, in some ca…
Gouy phase for full-aperture spherical and cylindrical waves
Tomas Tyc
We investigate the Gouy phase shift for full-aperture waves converging to a focal point from all directions in two and three dimensions. We find a simple interpretation for the Gou…
