1. An X-ray converter comprising:a light-proof housing, one of whose walls is X-ray transparent, and the following units fastened one after another behind this wall:an X-ray-to-optical converter of the X-radiation into visible light,a filter of residual X-radiation,an unit of objective lenses, each of which contains at least two one by one installed lenses for focusing a part of the light flux on the corresponding optoelectronic converter, anda photodetector containing at least two optoelectronic converters having partly overlapping fields of view and separated electrical outputs for connection to a system for fragmentary video signals processing and their “sewing together” into an integral output video signal, characterized in thatthe light-proof housing is equipped with an additional light-opaque and X-ray-opaque partition that has through-holes, whose number and placement correspond to the number and placement of objective lenses and optoelectronic converters, and is rigidly fastened within said housing practically parallel to the X-ray-to-optical converter,the filter of residual X-radiation formed as washers that are made from an X-ray opaque light-transparent material and rigidly fastened within said through-holes of the additional partition,said additional partition is equipped with blinds, whose number and placement correspond to the number and placement of objective lenses and optoelectronic converters; these blinds are installed on such side of this partition that is opposite to said X-ray-to-optical converter, andlength A of each blind and distance D from the front (following the pass of X-rays) surface of said X-ray-to-optical converter to the plane of front (following the pass of light) end faces of objective lenses are related by the ratio A/D=(0.50-0.95). 2. The X-ray converter of claim 1 characterized in that said ratio is of A/D=(0.55-0.90). 3. The X-ray converter of claim 2 characterized in that said additional partition comprises of a lead plate and a supporting plate made from suitable rigid material. 4. The X-ray converter of claim 3 characterized in that each objective lens is equipped with at least one diaphragm for restriction of the light flux. 5. The X-ray converter of claim 4 characterized in that each objective lens has three diaphragms installed ahead of the input lens, between lenses, and after the output lens. 6. The X-ray converter of claim 2 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings. 7. The X-ray converter of claim 1 characterized in that said additional partition comprises of a lead plate and a supporting plate made from suitable rigid material. 8. The X-ray converter of claim 7 characterized in that each objective lens is equipped with at least one diaphragm for restriction of the light flux. 9. The X-ray converter of claim 8 characterized in that each objective lens has three diaphragms installed ahead of the input lens, between lenses, and after the output lens. 10. The X-ray converter of claim 9 characterized in that interior of the side housing walls, blinds on the inside, and diaphragms on both sides have black matte coatings. 11. The X-ray converter of claim 9 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings. 12. The X-ray converter of claim 8 characterized in that interior of the side housing walls, blinds on the inside, and diaphragms on both sides have black matte coatings. 13. The X-ray converter of claim 12 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings. 14. The X-ray converter of claim 8 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings. 15. The X-ray converter of claim 7 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings. 16. The X-ray converter of claim 1 characterized in that surfaces of said washers of the filter of residual X-radiation and the lenses of said objective lenses have anti-reflecting coatings.
