Multifocal photon-sieve with Bessel-Gaussian distribution of pinholes

Abstract:   (883 Views)

In this paper we try to use Bessel-Gaussian function to create damping oscillating distribution of pinholes in photon-sieve. This function concentrates the density of pinholes in some Fresnel zones and vanishes in some parts. Thus, by preserve the phase distribution function, a kind of spacial filtering exerts to modulating the diffracting beam in desired way. As the consequence of this modulation, the satellite focal points will be appearing in direction of optical axis. Experimental results in coherence imaging setup with input plan wave confirms the initial assumption.

Keywords: Fresnel zone plate, photon-sieve, Bessel-Gaussian function, spacial filter
