Fresnel zone plates (FZPs) are widely used for X-ray focusing and imaging thanks to their compactness and high resolution compared to refractive or mirror-based X-ray optics. However, achieving high ...

A photon sieve containing pinholes that follow a fractal pattern produces high quality images. optics.org talks to Walter Furlan to find out more about fractal photon sieves. A fractal photon sieve ...

“Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date ...
