A quantitative evaluation algorithm for the optical initial structure based on massive data comparison and selection

A good initial structure is the necessary foundation for accomplishing an excellent optical design. For now, the judgment of the initial structure is mostly based on the experience of the designers, lacking an effective quantitative assessment methodology. In this paper, the non-displacement zoom system is taken as an example, and a quantitative evaluation algorithm for the optical initial structure based on massive data comparison and selection is proposed, which can evaluate the optimization potential of different initial structures based on the design objectives, screen out the optimal initial structure parameters, and modify the original initial structure according to the selected parameters to make it more capable with the target design requirements. The whole calculation process does not involve the aberration theory, and the final constructed initial structure also shows good optimization potential and stability in the subsequent optimization. The method is simple, easy to understand, highly efficient, and can be easily extended to other types of optical systems, which is friendly to inexperienced designers and is expected to provide new direction for the development of current optical design methods.
