Designing Illumination Lenses and Mirrors by the Numerical Solution of Monge-Ampère Equations
Kolja Brix, Yasemin Hafizogullari, Andreas Platen
We consider the inverse refractor and the inverse reflector problem. The task is to design a free-form lens or a free-form mirror that, when illuminated by a point light source, pr…
Empirical Study of the 1-2-3 Trend Indicator
Yasemin Hafizogullari, Stanislaus Maier-Paape, Andreas Platen
In this paper we study automatically recognized trends and investigate their statistics. To do that we introduce the notion of a wavelength for time series via cross correlation an…
Solving the Monge-Ampère Equations for the Inverse Reflector Problem
Kolja Brix, Yasemin Hafizogullari, Andreas Platen
The inverse reflector problem arises in geometrical nonimaging optics: Given a light source and a target, the question is how to design a reflecting free-form surface such that a d…
