“…Moreover, multiple freedom degrees of the sag provide diffractive optical element (DOE) with strong ability to correct the aberration of an optical system. Researchers have validated its on-axis and off-axis wavefront control ability in membrane mirrors 23,24 . Based on this consideration, diffractive optical element has been widely used to correct the aberration in optical image system.…”

Metasurface, fluorescent microscopy and scanning near-field optical microscopy can improve the resolution of microscopes remarkably, while the resolution of the telescope remains unimproved constrained by its giant objective lenses and distant targets. Here we put forward a way to raise the resolution of telescopes simply by adding a binary optical thin surface around its focal plane. Simulation results show that the surface can raise the image quality in the Cassegrain and Kepler telescope. By nano-lathe, we fabricated a designed binary surface and experiment it in the Kepler telescope. The results are consistent with those of simulation results. More details of the calibrated target are resolvable on the image plane after applying the binary optical surface. It proves that the binary optic surface can make contribute to the resolution of the telescope, thus is beneficial in astronomy, military surveillance field.
