title = "Ultra-precision freeform surface evaluation using genetic algorithm optimization",
abstract = "Freeform surfaces have been widely used in industry and daily life for their unique optical properties. To meet the required performances, they are usually needed to be manufactured with extremely high form accuracy. To obtain the form error, one of the main challenges is to match the measured surface data with theoretical model. However, due to the surface complexity, matching results may be trapped at a local minimum. In this proposed paper, a high efficient iteration method was developed to calculate closest point on the designed surface to the measured point and genetic algorithm has been proposed to find out the optimized motion parameter. From the experimental results, it can be seen that the form error caused by the evaluation algorithm can reach nanometric level.",
