WebA photon sieve is a revolutionary optical instrument that provides high resolution imaging at a fraction of the weight of typical telescopes, with an areal density of 0.3 kg/m 2 … WebIn contrast, photon sieve (PS) is a zone plate in which open zones are replaced by a given distribution of pinholes [2]. Generally speaking, the purpose of introducing PS was to increase the resolution as well as suppress the higher diffraction order of PS in comparison with the zone plate. Most importantly, PS opened up a new horizon in ...

As ex-pected, the photon sieve focused the collimated light onto a focal spot 1 m away. The ratio of the total power in the focal spot to that incident upon the pho-ton sieve was 0.35%. The performance of the photon sieve was then evaluated in several ways, by focus-
