Claim 0:
1. An x-ray detector device for industrial workpiece measuring by means of X-ray radiation, the x-ray detector device comprising
scintillator means (12) for converting incident X-rays of the X-ray radiation penetrating a workpiece to be measured into visible light at a scintillator light exit surface (14), optical detector means (22; 24, 26) for converting the visible light at the scintillator light exit surface into an electronic image signal, the optical detector means being disposed optically downstream of the scintillator means
and X-ray protection means (18, 20; 18′, 20′; 18″, 20″) disposed in an optical ray path between the scintillator means and the optical detector means and comprising a body which is transmissive to visible light and has X-ray-absorbing properties, wherein the body is a glass body,
wherein
the body is composed of multiple sheets and/or multiple layers, its material is selected in terms of X-ray absorption, transmission of visible light and resistance to material degradation, and its thickness is dimensioned in such a manner that a first sheet or layer (18; 18′; 18″), which faces the scintillator means, has greater X-ray-absorbing properties and/or a higher resistance to material degradation by the X-ray radiation than a second sheet or layer (20; 20′; 20″), which is disposed optically downstream of the first sheet or layer and faces the optical detector means,
and/or
the body is assigned regeneration means (30, 32) capable of introducing short-wave visible light radiation and/or UV radiation into the body to reduce X-ray-related material degradation in the body.
