The automated design of imaging systems involving no or minimal human effort has always been the expectation of scientists,researchers and optical *** addition,it is challenging to choose an appropriate starting point for an optical system *** this paper,we present a novel design framework based on a point-by-point design process that can automatically obtain high-performance freeform *** framework only requires a combination of planes as the input based on the configuration requirements or the prior knowledge of *** point-by-point design framework is different from the decadeslong tradition of optimizing surface *** 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 design process significantly reduces the amount of human effort required and does not rely on advanced design skills and *** demonstrate the feasibility of the proposed design framework,we successfully designed two highperformance systems as *** 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,telescopy,microscopy,spectroscopy,virtual reality and augmented reality.
