Improved Zone Plate Coded Imaging Technique by Using Four Special Designed Gabor Zone Plates

Direct-current component, high-order artifacts, and side lobe distortion provide serious drawbacks in the application of Fresnel zone plate coded imaging (ZPCI). The presentation provided here proposes a novel way to resolve all the above-mentioned problems. ‘Four different Gabor zone plates are suggested to substitute the one Fresnel zone plate used in the conventional ZPCI. Perfect reconstruction will be obtained when integrally analysing the four coded images. Primary numerical simulation provided here shows good result.
