In the field of aperture coding super-resolution imaging, an important reason limiting the image super-resolution effect is that aperture coding greatly reduces the incident light flux of the system. Phase wavefront encoding modulation technology can effectively increase the system light flux and improve image super-resolution results. However, using phase wavefront coding instead of aperture coding will cause complex frequency domain calculations. In this paper, the feasibility of the single-seam phase encoding pattern is proved through the mathematical calculation of phase wavefront coding modulation. In the subsequent reconstruction process, the Fourier ptychographic (FP) imaging algorithm is used for verification. The resolvable line pairs of the USAF are increased from Group0 Number2 to Group1 Number3, means the image resolution is approximately doubled. The optical system built based on this phase mask prove the luminous flux of the acquired down-sampled image is increased about more than 5 times, and the image signal-to-noise ratio (SNR) is increased about more than 7 times. This makes it possible for higher super-resolution computational imaging.
