PURPOSE:To freely execute stereo-single photographing and clairvoyance, by placing a television camera in the rear of a half-mirror, and 2 cinecameras on the right and left, and operating this half-mirror so as to move back and forth and to rotate. CONSTITUTION:X-ray fluoroscopic images for both a right image and a left image are obtained by alternately switching 2 focuses of an X-ray tube 1 of 1 targe and 2 focuses of generating X-rays by thermionic rays from 2 cathodes Kr, Kl which are separated from each other by an interval of human eyes. It is formed on an image intensifier 3 and is converted to an optical image. On its rear optical path, a half-mirror 4b for 90% reflection and 10% transmission, which is movable back and forth, and is rotatable is provided, 90% of light beams are divided and are made incident to 2 cinecameras 5 and 6, and the residual light beams are led to a television cemera 7 placed in the rear. In case of clairvoyance, the half-mirror 4b is retired so as to lead the optical image directly to an image pickup tube of an X-ray television set. |
