    Prospect of medical endoscope technology

        Medical endoscopy has promoted the continuous development of medical career in different periods. In the future, with the continuous progress of electronic technology and other science and technology, I believe its technology will have a broader and deeper development. It can not only complete any work completed today, but also provide new diagnosis and treatment image information with CCD with special spectrum. It can also obtain special images of diseased tissue with image processing technology, realize quantitative analysis and diagnosis of diseased tissue with image analysis technology, and carry out remote consultation by means of telecommunication. Multifunctional electronic endoscope has come out. It can not only obtain the morphological diagnosis information of tissues and organs, but also measure various physiological functions of tissues and organs. Today, the development of medical endoscope technology has shown its strong vitality. I believe it will make more brilliant contributions tomorrow.

    Industrial flaw detection technology of endoscope

    Nondestructive testing technology of industrial endoscope

    T922 special video endoscope for pipeline

        The above is mainly about the application of endoscope in medical examination. In fact, there are more advanced G-tube endoscopes in industry. In terms of nondestructive testing and hole detection technology, LED electronic medical endoscope detector and industrial pipeline video endoscope are widely used in automobile repair, security, security inspection and other fields

        From the imaging form is divided into: hard tube industrial endoscope, hose industrial endoscope, image industrial endoscope.

        Many achromatic optical lenses (optical system as shown in the figure below) are installed on the axis of the rigid tube industrial mirror to form an image transmission system, which can obtain high-quality images and transmit them to the detector's eyes without distortion, so the imaging is very fidelity, and it is also the highest definition of these mirrors.

        The flexible small diameter flexible tube endoscope can deeply inspect the places that hard tube industrial endoscope can't reach. The biggest difference between the flexible small diameter flexible tube endoscope and the hard tube industrial endoscope is that the soft optical fiber is used to form the image transmission system (the optical system is shown in the figure below). Once the light enters the optical fiber, it can't escape. Therefore, the rotation or bending of the endoscope axis will not affect the image transmission In other words, the image resolution depends on the number of optical fibers. The more the optical fibers are, the smaller the diameter is, the higher the image resolution will be. Of course, the manufacturing cost will also increase. The number of optical fibers of the windable industrial endoscope can be up to 22000 from 3500. For the convenience of observation, there are also two and four direction control models that can control the front-end shaft to change different viewing angles.

        The image industrial endoscope uses a photosensitive chip less than 1 %/ 6 %which is located at the axis end of the endoscope to take the image directly and transmit it to the monitor for imaging through the signal transmission line. Because the image is directly converted into an electrical signal, the endoscope can not be directly visualized, and the lighting is directly illuminated by LED located at the axis end. The advantages are that the manufacturing cost is relatively low and has nothing to do with the axis length, the screen observation is easy, and the pictures can be stored The video recording is based on off-line analysis; the disadvantage is that due to the fact that the photosensitive chip is located at the shaft end, the shaft diameter of the endoscope is 1 %/ 18 %, and the smallest photosensitive chip can only reach about 5.5mm (it can withstand 10m water pressure and integrate high brightness LED light). If the reliability requirements are properly reduced, it can reach 3.8mm. In addition, the environmental resistance is poor, the allowable temperature resistance and shock resistance are not as good as the optical endoscope, so it can not be used in various occasions.

        Principle of nondestructive testing for industrial endoscope

        Industrial endoscope is a branch of non-destructive testing, it can also be said that it is a special testing technology.

        Because of its special size design, the industrial endoscope can easily and accurately observe the internal surface structure or working state of the object without damaging the surface of the object to be detected.

        Industrial endoscopy can be used for inspection and observation of high temperature, toxic, nuclear radiation and places that can not be directly observed by human eyes. It is mainly used for automobile, aero-engine, pipeline, mechanical parts, etc. it can realize non-destructive testing without disassembly or destruction of assembly and equipment stop running. On the other hand, industrial endoscopy can also be connected with camera, video camera or electronic computer In order to monitor, record, store and analyze the field of view objects, a system of photographing, photographing and image processing is formed.
