Problems solved by technology

[0005] The common disadvantage of the three types of equipment is the lack of radiation resistance, because the imaging system inevitably needs to use optical glass, imaging components, and electronic devices, and these materials will produce defects or even fail under the irradiation of gamma rays
Because of the intrinsic nature of this defect, any viewing device that directly exposes optics, imaging components, or electronics to a radiation field will eventually fail under the rays

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] Such as figure 1 As shown, the present invention is installed in a radioactive place, and the lens barrel is formed by connecting the front end lens barrel 2-1 and the lens barrel body 2-2 through the rotation and pitch mechanism 4, and the lens barrel body 2-2 and the lens barrel body 2-2 are arranged on The optical imaging components 1 inside are all buried in the shielding wall 5, so that all optical lenses and imaging elements are in good shielding, and the inner wall of the lens barrel is roughened. The roughening process of the inner wall in this example is to process the inner wall of the lens barrel It has a thread-like structure and is coated with black coating, which eliminates the specular reflection inside the lens barrel and improves the image quality. Utilize the mirror 3 arranged at the front end of the lens barrel to chan...

Abstract

The invention discloses a radiation resistance pickup observing device which comprises an optical imaging part and a lens cylinder. The radiation resistance pickup observing device is characterized in that the lens cylinder is arranged in a barrier shield wall, the optical imaging part is arranged in the lens cylinder, and a retroreflector is arranged at the front end of the lens cylinder. The radiation resistance pickup observing device is simple in structure, strong in radiation resistance capacity, low in cost, and high in observing definition.

Description

technical field [0001] The invention relates to the technical field of radiation, in particular to a radiation-resistant camera and observation device used in a radiation workplace. Background technique [0002] The field of nuclear industry involves a lot of radioactive work. In the fields of nuclear fuel / material post-irradiation inspection, radioactive source packaging / preparation, and nuclear fuel reprocessing, it is necessary to operate objects with extremely high radioactivity. It is operated at a long distance under the premise of good shielding. Traditionally, long-distance operations are observed through lead glass peep windows. This kind of observation is not intuitive, the clarity of observation and the three-dimensional sense of space are not ideal, especially the details of the operated objects cannot be observed, so the developed Different types of radiation-resistant observation equipment, such equipment mainly include periscopes, industrial cameras, radiatio...
