Proceedings PaperRank-down method for automatic lens design
|Format||Member Price||Non-Member Price|
A new automatic lens design method using singular value decomposition (SVD) is proposed. This method enables the designer to reflect his own intention in optimization via the Rank Down Constant introduced in this paper. This characteristic also makes it possible to accelerate the optimization. An example showing the high performance of this method is demonsirated. Some useful applications of S. V. D. are also proposed. 1 .
