摘要

Abstract

The automated design of imaging systems involving no or minimal human effort has always been the expectation of scientists

researchers and optical engineers. In addition

it is challenging to choose an appropriate starting point for an optical system design. In this paper

we present a novel design framework based on a point-by-point design process that can automatically obtain high-performance freeform systems. This framework only requires a combination of planes as the input based on the configuration requirements or the prior knowledge of designers. This point-by-point design framework is different from the decades-long tradition of optimizing surface coefficients. Compared with the traditional design method

whereby the selection of the starting point and the optimization process are independent of each other and require extensive amount of human effort

there are no obvious differences between these two processes in our design framework

and the entire design process is mostly automated. This automated design process significantly reduces the amount of human effort required and does not rely on advanced design skills and experience. To demonstrate the feasibility of the proposed design framework

we successfully designed two high-performance systems as examples. This point-by-point design framework opens up new possibilities for automated optical design and can be used to develop automated optical design in the areas of remote sensing
