Paper Abstract

We analyze an optical system consisting of a number of basically elements (BE) arranged in a quasi-periodic structure (QPS) of phyllotaxis type, which offers the best packing in many natural bodies. In our simulations, we change the parameters which generate this QPS to find its diffractive optical properties. This structure is then made on glass using e-beam lithography. To characterize this QPS, we use the digital holography (DH) method to reconstruct the amplitude and also the phase in object plane (QPS plane). Using different parameters of the spherical reference wave for holograms recording we change the contrast in holograms to improve the reconstruction of the object.
