A method for producing multilayered optical filters, comprising a method for operating a genetic algorithm

摘要

The present invention extracts each layers of nickel Di (2-6) multilayer optical filter of the refractive index and thickness of optimal combination. Matrix P=(X1, X2, X3 is expressed as generating initial pattern, in addition, it is free on board) it include the multilayer optical filter that first equal matrix Xi includes the layer i of refractive index and thickness, the Catastrophe Model of the process of reproduction and mutation is used to generate first part Xi initial pattern execution task by increasing or reducing refractive index and thickness. Matrix pattern is substituted to being performed a pair of of pattern for selecting of bridging includes Catastrophe Model and initial pattern from one group. The optical characteristics that there is method choice highest pattern to select closer to desired characteristic is analyzed in initial pattern, the pattern groups of mutation, and across pattern groups. Then algorithmic procedure includes that succession of steps repeats selected pattern of the above procedure relative to predetermined quantity, and the optical characteristics until finally selecting pattern is caught in the meshes of law the desired optical characteristics of required error range, to generate best multilayer optical filter.
