AbstractA method for designing a class of phase-only super-resolving filters with continuous-phase that can be described by a sum of Zernike polynomials with weight coefficients is presented. With the use of the global search algorithm, differential evolution method, and the local search algorithm, the conjugate gradient method, three filters were designed as examples. The main-lobe size of the point spread function of the three filters can be reduced, keeping allowable central intensity and sidelobe intensity for some typical applications. This type of filter has the advantage of lower scatter compared with other phase-only filters composed of discontinuous phase. In particular, such filters can be implemented dynamically by a phase-controlling device. © 2016 Society of Photo-Optical Instrumentation Engineers (SPIE).
