What is Borescope

In the field of non-destructive and ocular or visual tests, a boracoscope is an optical or optical instrument consisting of a rigid or flexible tube with a section containing an ocular lens for viewing objects in inaccessible locations and an end section containing an objective lens on the other side. The lens is connected to each other by an optical system consisting of a light source and optical fiber walls to allow one to see inaccessible objects. In advanced models you will be able to see images on the monitor as video, something like endoscopy in medicine.

applications

Boracoscopes are used in technical inspections where access to them may require breakdown or time consuming and are used to see defects in various gas, petrochemical and aerospace industries. Boracoscopes, for example. Visual inspection of aircraft engines, industrial gas turbines, water vapor turbines, steam turbines, diesel engines, and car and truck engines are used, and in maintenance, gas turbines can prevent unnecessary repairs that may be necessary for Large turbines are very expensive. They are also used in the manufacture of machining or casting parts to inspect vital internal surfaces before the holes are completed or completed. Other common uses include legal applications in law enforcement and building inspections, as well as in the Law on Prohibition of Weapons embedded in internal cavities, and so on.

A flexible broscope is made up
of a set of optical fibers to divide the image into pixels, also called a fibroscope, and can be used to access holes around curves, such as a combustion chamber or "steam burner." And in order to observe the condition of compressed air inlet, turbine blade and separation packing of engine parts should be used.
The quality of flexible borescopes varies greatly between models depending on the number of light fibers and the construction used in them. Some high-end broscopes offer an "image grid" in the image to evaluate the size of each area To be. For flexible borescopes, the components of the joint mechanism, the amplitude and range of operation, the field and the viewing angle of the target lens are also important. The performance range of borescopes is at least 10,000 pixels, while the best images with more fibers in the range of 15,000 to 22,000 for large diameter broscopes can be. The ability to control the light at the end of the tube allows the bishop to adjust settings that can greatly improve the resolution of video or still images.

Video
Boscope A video borescope or "inspection camera" is similar to a flexible borecope, but uses a miniature video camera at the end of the flexible tube.

The end of the injection tube contains a light that allows video or photos of the two parts to be accessible within equipment, engines and other dark spaces. As a tool for remote inspection, the ability to record video or still images for subsequent inspections is a very good possibility. The screen is embedded in the handle as a camera display, and the position and position of the visible subject can be changed through the joystick control or similar controls.

Due to the complexity of the optical waveguide and the possibility of working similarly with a cheap electric cable, it can be a good alternative to fiber optic models. The video viewfinder can be much cheaper and with potentially better resolution (depending on the camera specifications). The cost of a high video broscope can be between $ 8,000 and $ 50,000 depending on the manufacturer, options and specifications.
Using rechargeable batteries, using a 3-inch screen with a resolution of 320 x 240 pixels or better, since 2012, several manufacturers have been using it for prices between $ 100 and $ 400 for some applications. In many of these models, the camcorder and the tube are flexible. Later models offer advanced features such as lower costs, better resolution or the replacement of the internal screen with a computer connection, such as a USB cable. Models for this type of entertainment are currently available for around $ 10.

Bvrskvp non-flexible or rigid carbon fiber is similar to, but generally a superior image with a lower cost than a Bvrskvp flexible offers. Of course, rigid borscopes have a limit that access and what is seen must be in a straight line. Therefore, a smooth borescope is suitable for certain tasks such as inspecting car cylinders, fuel injectors and hydraulic objects, and weapon making.
The criteria for choosing a boroscope is usually image resolution and accessibility. For similar quality tools, the largest inflexible borescope that reaches the right hole gives the best image. Optical systems in rigid and rigid broscopes can be of three main types: Harold Hopkins lenses, achromatic doublet lenses, and gradient index lenses. For large diameter borescopes (over 12mm), achromatic models work well, but as the diameter of the brushcope tube gets smaller, Hopkins rod lenses and gradient star lens designs provide better images. For very small inflexible microprocessors (less than 3 mm), gradient index lens relay is better
