【Abstract】 A new optimization approach to function parameters of pupil filter based on adaptive real-coded genetic algorithm is proposed. Out of consideration of practical need for optical energy efficiency, sidelobe intensity, and superresolution, the appropriate parameters are selected by means of the computer simulation to achieve the best axial superresolution. By using adaptive real-code genetic algorithms, the design of pupil filters becomes simpler and possesses better comprehensive effects. The pupil filters designed with the aid of adaptive real-code genetic algorithm possess smaller u₀,M and larger S. It is verified by the theory and practice that this method is highly effective and reliable.更多还原
