Description
Recently, high resolution micrography became of great interest. Very thin scintillator layers of about 5-20 micrometers are used to achieve spatial resolution below one micrometer in application for low energy X-ray micro-radiography. Such thin screens are mainly used in micro-CT and nano-CT systems with either micro-focus X-ray tubes or with synchrotron sources.
This work deals with a high resolution CCD camera together with different optical systems and different single crystal scintillators in application for low energy X-ray micro-radiography. The light distribution on the screen is transferred by an optical system to a high-resolution CCD or CMOS chip. A theoretical modeling and practical comparison of several set-ups has been done to investigate the system resolution limits. Thin screens used were prepared from different scintillators. The resolution is presented on test patterns.
