The principle of non-destructive testing of industrial endoscope industrial endoscope, is a branch of non-destructive testing, it can be said to be a specialized detection technology. Because of its special industrial endoscope sized portable car endoscope allows us easy to be detected without damaging the surface of the object, the object accurately observe the inner surface of the structure or work status. Requires the use of non-destructive testing of industrial endoscope as a detection tool, in order to meet the industrial complex environment and professional design and production. Endoscopic detection in recent years with the development of manufacturing technology of endoscopic gradually been widely used as a detection technique. According to the characteristics of the manufacturing process, we generally industrial endoscope into the tube lens optics, optical microscopy, video microscopy three types. Industrial endoscope can be used to check the temperature and observation sites, toxic, nuclear radiation and the human eye can not be directly observed, mainly for the automotive, aerospace engines, pipes, mechanical parts, etc., can be assembled and without dismantling or destruction of equipment stop running conditions to achieve non-destructive testing, on the other hand industrial endoscope can also be connected with the camera, camcorder or computer, composed of photography, video and image processing systems, which were field goals of monitoring, recording, storage and map like analysis provide a good guarantee for the diagnosis and treatment. Industrial endoscope is also used to periodically check the aircraft turbine blades, the engine, the weld surface, the catheter surface, inside the combustion chamber or body checks and rocket engine research and development, manufacturing. It does not break down as the only one capable of understanding the engine and check the status of the auto industry means its internal endoscope, which has important significance and value in both safety and efficiency. Through timely detection of industrial endoscope can be found ahead of the relevant risks, make timely resolution of the bill, it has safety significance. Industrial endoscope is not disassemble and inspect the relevant parts, so it can not only improve efficiency, while reducing maintenance costs.
