Abstract
Abstract An introscope is disclosed wherein penetrating radiation passes through a test object with reference marks set thereon and enters an main and an additional fluoroscopic converters, which transform the penetrating radiation into main and additional fluxes of visible light carrying information on the shadow interior of the test object. One of said fluxes, the main one, after being reflected from a main mirror, is transmitted to a photocathode of an image converter and after amplification of the light therein is transmitted to a photocathode of a pickup tube of a closed-circuit television system, whereas the other of said fluxes, the additional one, is reflected from an additional mirror and is transmitted to a cinema recorder. The luminescence spectrum of the additional fluoroscopic converter is different from the luminescence spectrum of the main fluoroscopic converter. The monitor screen of the closed-circuit television system and the film of the cinema recorder show a picture of the interior of the test object, the image on the monitor screen being corrected through the use of the reference marks on the film image.
