The endoscope is an optoelectronic device used to probe the internal condition of the object being examined. It is divided into medical endoscopes and industrial endoscopes.
The working principle of the endoscope is that a tiny probe is sent into the interior of the inspected object, and then the internal image is transmitted to the exterior of the inspected object through the optical imaging principle (a set of lenses) or the electronic imaging principle (photoelectric sensing device such as a CCD), and the inspector can see the interior of the inspected object through the eyepiece or the monitor and other equipment in real time.
In the medical field is mainly enteroscopy, gastroscopy, such as inspection, to check the human body organs have no disease; industry is mainly on the engine, transmission, pipeline and other human eyes are difficult to directly see the internal non-destructive testing of the equipment, check for defects (corrosion, cracks, obstruction, etc.), do not have to dismantle the equipment.
Compared with other means of inspection, the main advantage of endoscopy is that there is no damage or minimal damage, can be viewed in real time, and the effect is intuitive. Like the industrial use of Weylin industrial endoscope, the image is very clear, to industrial equipment inspection provides great convenience. The following figure is the inspection site map, you can see the inspector's left hand will be sent into the equipment inside the probe, and then you can watch in real time in the handheld screen shows the detection of the image, very intuitive.
