An optimization method for radial NURBS surfaces

Werner, Jürgen; Hillenbrand, Matthias GND; Zhao, Mingcheng; Sinzinger, Stefan GND

We study the use of non-uniform rational B-splines (NURBS) for describing axially symmetric surfaces in the design of imaging optical systems. We suggest a representation using a base sphere with an additional NURBS curve. We present an optimization method for such surfaces based on the local structure of NURBS.
