Helmholtz-Zentrum Geesthacht (HZG) is operating the microtomography stations using synchrotron radiation at DESY, Hamburg. Absorption contrast and phase contrast techniques were developed and applied to samples in the fields of medicine, biology, and materials science. The present work is devoted to the development of an intelligent detector with high-speed data capturing for experiments for grating based phase-contrast imaging. The detector is based on the Ultra-fast streaming camera platform developed at the Karlsruhe Institute of Technology (KIT). Characterization (in terms of photon transfer curve) of some different cameras, such as CMOS and CCD, is presented. These characteristics are required to optimize the operation of the detector according to the one or to the other requirements of processing speed and image quality in the course of phase-contrast imaging process.The detector will be optimized to its implementation at the microtomography setups installed at the beamlines IBL and HEMS of the high brilliant third-generation synchrotron light source PETRA III.
