Van Turnhout, M. Faculty Applied Sciences Department Optics Research Group Date 2009-08-21 Abstract Contrary to the frequent tacit assumption that the local minima of a merit function are points scattered more or less randomly over the design landscape, we have found that, at least for simple imaging systems (doublets with three and triplets with five variables) all design shapes we have observed thus far form a strictly ordered set of points, the “fundamental network”. The design shapes obtained for practical specifications with global optimization algorithms are a subset of the set of local minima in the fundamental network and are organized in a way that can be understood on the basis of the fundamental network Subject saddle pointglobal optimizationoptical system design To reference this document use: http://resolver.tudelft.nl/uuid:5aa7303a-d75f-4893-9549-320ddf741662 Publisher SPIE ISSN 0277-786X Source Proceedings of SPIE, 2009 vol. 7428 Part of collection Institutional Repository Document type conference paper Rights (c)2009 Van Grol, P., Bociort, F., Van Turnhout, M.
