Design Feasibility Study for a Demultiplexer Miniaturized for Microtomographic Imaging

Publication date: 2017 Source:Physics Procedia, Volume 88 Author(s): Udo Lang, Pavel Trtik, Manuela Notter, Jan Hovind, Eberhard H. Lehmann In this paper a design feasibility study of a miniaturized demultiplexer that allows for simultaneous tomographic imaging on three independent rotational axes. While the general concept has been proven on a larger scale for three centimeter sized samples, the downscaling of this concept is presented herein. The main requirements are firstly, positioning of the samples parallel to the detector screen for stable imaging and secondly, the use of backlash free gears to avoid any angular play. Based on these requirements a concept is shown that consists of three precisely positioned anti-backlash axes within a housing with a spacing of 3.5mm.
