The industrial endoscope is an NDT instrument integrating electronic technology, optics, precision machinery, and micro camera technology,which is mainly used to detect equipment and parts that cannot or are difficult to be observed by the human eye, such as pipes, machinery, and automobiles,which helps the inspector to quickly and accurately identify and judge defects.

According to the requirements of aircraft maintenance manual and airworthiness instructions, industrial endoscope is often required, which is a very intuitive detection method to clarify the status of aircraft.

For food, pharmaceutical and other industries, pipeline system is a very common component, and there are very high cleanliness requirements, unqualified pipeline welding quality and wrong evaluation of high cleanliness, which may lead to high and irreversible costs: bad consequences (even personal injury) caused by contaminated products entering the market

Industrial endoscope is of great significance to the safety and effectiveness of aircraft. Through industrial borescope inspection, the engine disassembly, replacement, transportation and unnecessary shutdown losses are avoided, and the maintenance cost is saved. At the same time, the videoscope observation is intuitive, accurate, easy to operate, and can detect the internal damage of the engine in time.

A widely used visual inspection instrument at present is video endoscope, which is also one of the important methods in non-destructive testing. It is usually used to observe the surface state, alignment of mating surfaces, signs of deformation or leakage, etc., such as parts , components and equipment, etc.

Generally, aircraft engine endoscopy is divided into three types: routine inspection, targeted inspection and expanded area inspection. The importance of industrial endoscope in aero-engine inspection records is mainly reflected in the following three aspects:

The hose endoscope is mostly used in the field of police. It is used for security inspection, explosive disposal, anti smuggling, criminal investigation, search and rescue and other work in major organs and units. It can be used in public security, fire protection, armed police, procuratorate, customs and other organs and units.
