The optical fiber endoscope is composed of a certain number of optical fiber bundles. Because the optical fiber is relatively slender, after a long time of bending and use, the optical fiber will be easily damaged and broken, and black spots will appear in the imaging, which affects the endoscope.

Industrial endoscope is a kind of non-destructive testing equipment widely used in industrial manufacturing and maintenance at present. It extends the visual distance of the human eye, breaks through the blind angle of human eye observation, and can accurately and clearly observe the inside of machinery and equipment or parts.

An industrial endoscope is a visual inspection equipment that integrates advanced technologies in various fields such as electronics, optics and hardware. The front end can be bent and manipulated with the probe and pipe section, which can effectively increase the viewing distance and change the direction of the line of sight.

Domestically, industrial endoscopes were introduced from abroad in the 1970s, mainly used for internal redundant control of aerospace products and quality inspection of some parts.

The key components of the engine, such as the main air flow channel components, high-pressure compressor, high-pressure and low-pressure turbine discs and blades,

Police endoscopes are widely used in the fields of criminal investigation, security, EOD, anti-drug, anti-smuggling, and search and rescue. Because police scopes have many advantages that are not available in investigative instruments or equipment. On the one hand, because of its concealment, it can enter the area that needs to be observed through a small gap.

All objects whose temperature is higher than absolute zero are constantly emitting infrared radiation energy into the surrounding space.
