Micro-Fresnel zone plates for coded imaging applications.
Design considerations and fabrication procedures for Fresnel zone plates appropriate for high-resolution coded imaging of x-ray and particle emission from laser produced plasmas are presented. Fabrication results for free standing zone plate structures of high Z material (gold), large zone number (100</=n</=240), microscopic minimum linewidth (2.6</=Deltar</=10.2 mum), and appreciable material thickness (1</=t</=7 mum) are reported.
