ABSTRACT:
An x-ray imaging device. One surface of a flat single crystal CsI crystal is supported on an optically transparent support plate. The opposite surface, i.e. an x-ray illumination surface of the crystal is coated with an x-ray transparent optical reflector to provide an x-ray scintillation sandwich having an optical mirror at the x-ray illumination surface of the CsI crystal. An optical camera is preferably focused on the illumination surface of the CsI crystal. In a preferred embodiment an index of refraction matched optical adhesive is used at the x-ray illumination surface to attach the reflector and to reduce Fresnel reflections.
