Method for constructing initial structure of athermal optical system based on particle swarm optimization algorithm

Abstract

The present disclosure relates to a method for constructing the initial structure of an athermal optical system, specifically relating to a method for constructing the initial structure of an athermal optical system based on particle swarm optimization algorithm, which is used to solve the shortcomings of the current athermal optical system designs where optical design software heavily relies on the initial structure of the athermal optical system, and the construction of the initial structure does not consider the selection of optical materials, resulting in extremely low efficiency of the athermal optical system designs. The method for constructing the initial structure of an athermal optical system based on particle swarm optimization algorithm provides a new design concept for the athermal optical system, which achieves a reasonable match between optical materials and mechanical materials in the initial structure stage and improves the efficiency of subsequent design optimization.
