X-Ray and Particle Microscopy Using Fresnel-Zone Plates

摘要

Fresnel zone plates are being used for x-ray microscopy covering a broad spectra range (.1-100 keV). They are being used as diffractive focusing elements for high resolution (<< 1 mu m), soft x-ray (.1-3 keV) imaging, and as coded apertures (in a shadow casting mode) for moderate resolution (> 1 mu m), hard x-ray (1-100 keV) imaging applications.
