摘要
The present invention extracts the best combination of refractive index Ni and thickness Di of each layer (2-6) in a multilayered optical filter. A process of generating initial pattern expressed as a matrix P = (X1, X2, X3, .., Xs) comprising elementary matrices Xi including refractive index and thickness of the layer i of a multilayered optical filter, a process of reproduction and mutation for generating mutated patterns by increasing or decreasing the refractive index and thickness of the element Xi in the initial pattern, are performed. A process of cross-over for selecting a pair of patterns from a group consisted of mutated patterns and initial patterns to substitute matrices in the pattern pair are performed. A process of selection for selecting highest patterns having optical characteristics closer to the desired characteristics from within the initial patterns, mutated pattern group, and crossed over pattern group is performed. Then an algorithm process comprised of a sequence of the above process steps is repeated with respect to the predetermined number of selected patterns until the optical characteristics of final selected patterns fall into the desired error range for the desired optical characteristics, thereby producing the best multilayered optical filter.
