New challenges are arising for modern optical measuring systems with regard to the simulation and optimization of the measuring systems and assessment procedures. This is particularly true of form measurement systems for aspheres, freeform surfaces and the simulation of optical systems such as those used in modern camera systems, and complex optical measuring systems. Optimizing procedures which require Jacobian matrices are becoming ever more important. Depending on the number of parameters to be optimized, PTB's procedure considerably reduces the number of simulations required to compute the Jacobian matrices, and it allows the computing time to be drastically reduced. PTB's procedure can thus be used in inline systems. (Technology Offer 376)
