A novel X-ray imaging detector based on optical reading of photoluminescent color centers in lithium fluoride, LiF, is presented. Its main characteristics - i.e. high spatial resolution on a large field of view, wide dynamic range, versatility and simplicity of use - make it a high performance imaging detector for applications in X-ray microscopy, photonic devices, Extreme UltraViolet (EUV) lithography, and materials science, as well as in the characterization of intense X-ray sources, including Free Electron Laser (FEL). The peculiarities of the LiF imaging detector overcome some of the limitations of other commonly used ones, and can be exploited for X-ray microscopy in very simple configurations, such as lensless techniques, even for in vivo investigations of biological samples. Advanced optical microscopy techniques have been used to obtain highly-resolved microradiographies of biological specimens, performed in absorption contrast mode. Its peculiarities seem suitable also for use in phase-contrast experiments. The LiF-based detector versatility allows improvements in order to optimize its response and sensitivity. © 2009 World Scientific Publishing Co. Pte. Ltd.
