It is proposed to use non-linear programming and target programming method to design the horizontal, axial and three-dimensional resolution of the imaging system under the condition of the Strobel ratio S (maximum brightness ratio of the super-resolution model and the mainlobe of the Alley model) Ring-amplitude super-resolution pupil filter at the maximum respectively. The design models and examples of super-resolution optimization are given, and the results are validated by mapping. For sidelobes with super-resolution, the filter is applied to the confocal scanning system, which can effectively suppress the sidelobes and improve the imaging signal-to-noise ratio and contrast ratio. This scheme is applied to the design of amplitude-domain super-resolution filter and ring-shaped pure phase super-resolution pupil filter above three zones, which provides a reference for the design of super-resolution filter.
