Design strategy and management of aberration correction process for lens with high complexity index

Subject of Research. The strategy of designing optical imaging systems is defined, which consists in combining various design methods and is based on the theory of structural and parametric synthesis, ensuring the presence of the necessary correction parameters in the original optical system. The control of the correction of residual aberrations by using the correction capabilities of the scheme is considered. The composition of the evaluation function, recommendations for automated aberration correction, calculation of tolerances for the manufacture of an optical system, as well as the decision-making procedure for choosing the best optical scheme option are proposed. Method. The strategy is based on the analysis of the properties of optical imaging systems and their classification, followed by the determination of the system complexity index, as well as on the classification of aberrations and the development of methods for their correction. Main Results. An algorithm is proposed for implementing the strategy based on understanding the properties of the optical system and its correction capabilities. Analysis of the design specification for determining the complexity index of the optical imaging system, the choice of the optimal scheme and the correction capabilities of the scheme are determined. The composition of the evaluation function is considered. The “default” function evaluation and the function compiled by the user are compared taking into account the recommendations proposed in this paper. Practical Relevance. The implementation of the proposed strategy creates conditions for reducing the design time, especially for systems of increased complexity with forced technical characteristics. An algorithm flowchart is presented, its parameters and correction capabilities are determined. Automated correction is carried out based on the received recommendations. The tolerances for manufacturing are calculated and the level of its manufacturability is determined.
