Emerging Optics for X-ray Imaging
We are a multidisciplinary team with the aim to develop novel optical elements with two- and three dimensions for multi-modal information acquisition based on small-angle scattering, absorption and phase contrast. These elements should help to broaden the X-ray imaging modalities for biomedical and material science applications at synchrotron facilities and X-ray laboratories.
The current activities concentrate on process and methodology development to pattern the optical elements by various lithographic techniques, characterize and employ conventional and inverted Hartmann masks, as well as Shack-Hartmann sensors for investigation of dynamical processes. Furthermore, considerable research is devoted to enhance the synthesis of the polymer used in the lithography process to obtain better physical-chemical properties and to use the optimized formulation in the fabrication of high aspect ratio grating structures. The novel structures will be employed as the main optical elements in Single-Shot imaging modalities to investigate weak X-ray absorbing samples and composite materials with similar absorption cross-sections by phase and small-angle scattering imaging.
December 2018: The Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), of the Ministry of Science, Technology, Innovation, Communication of Brazil, has granted a scholarship for 11 months to Sara Ferreira da Costa to pursue Split Fellowship Program starting in March/2019 up to January/2020 at KIT-IMT under the scientific supervision of D. Kunka.
