Rigid Inspection camera structure principle
The structure of the rigid Inspection camera’s working principle is the use of transfer lens optical technology to transmit images, and by optical tube to provide light transmission lighting. In order to deliver a sharp image, a rotating lens system with several optical elements was designed in the effective stainless steel insertof the scope. The built-in fiber takes the photographic light directly from the independent cold light source to the working position. Product Specifications: Diameter 1 ~ 20mm, length 50 ~ 1000mm. The main uses in the aerospace industry are for the inspection of the body frame, regular inspection of the turbine blades and combustion chambers, and also for NDT work in the R & D and manufacturing of complete machines and components of aerospace engines. In other industries are also widely used.
Brazing dimensional structure of the borescope
Fiber borescope’s working principle is transmitted by a high-quality imaging fiber, like a direct observation through the eyepiece. The fiber borescope is composed of an insert HA, a bending part and a soft part, an operation part and an eyepiece part, all of the wires for transmitting the image fiber bundle, the optical fiber and the front-end swinging angle are all built- Cold light source. Specifications: Diameter 2.4 ~ 12mm, length 5 ~ 6000mm.
Beginning in the 1980s, foreign countries use ultra-small charge-coupled device (CCD) technology to manufacture electronic video borescope products. It is through the objective lens imaging to the CCD rake surface, then the CCD image and then converted into electronic signals, the data transmitted to the video borescope control group, and then the control group to the image output to the monitor or computer principle . China used the technology to manufacture electronic video borescope in the early 1990s. Product Specifications: Diameter 6 ~ 20mm, length 2 ~ 100m.
Electronic video Inspection camera technology level represents the most advanced level of borescope. It not only possesses the technical performance of hard borescopes and fiber borescopes, but also increases the computer application technology to allow many people to watch clear images at the same time, and has the functions of image measurement processing and the like. The electronic industry Inspection camera selected CCD image elements 280,000 ~ 430,000, high definition, effective length of work, the main body can be bent and not easily broken. Air China No.4, 2001 Aerospace and other industries are widely used. Because of the high price of the product, domestic users now use a large number of fiber Inspection cameras and rigid borescopes. For this situation, the domestic manufacturers continue to introduce foreign electronic industry borescope technology to produce products, reduce foreign exchange expenditures and improve the level of domestic NDT work
