In addition to the application of endoscopy in medical examination, there are more advanced pipeline endoscopes in industry.

廣泛的應用：

Wide range of applications:

從成像形式分為：硬管工業內視鏡、軟管工業內視鏡鏡、影像工業內視鏡。硬管工業內視鏡軸心裝有許多消色差光學鏡片組成影像傳遞系統，可以得到較高質量的影像，沒有失真的傳到檢測者的眼睛，所以成像非常的保真，也是這幾種鏡子中清晰度非常高的。

From the imaging form is divided into: hard tube industrial endoscope, hose industrial endoscope, image industrial endoscope. There are many achromatic optical lenses on the axis of the rigid tube industrial mirror to form an image transmission system, which can get high-quality images and transmit them to the detector's eyes without distortion, so the imaging is very high fidelity, which is also one of the high-definition mirrors.
                 

可繞式小直徑軟管內視鏡可深入檢查硬管工業內視鏡無法到達的地方，它與硬式工業內視鏡較大的差異為使用軟性光學光纖組成影像傳遞系統，光線一旦進入光纖后即無法逃脫，因此內視鏡軸扭轉或彎曲均不會影響影像傳遞;由于影像是由與光纖數目相同的「點」組成，亦即影像分辨率由光纖數目所決定;越多直徑越小的光纖其成像分辨率也越高，當然制造成本也隨之提高。可繞式工業內視鏡光纖數目可由3500條至高達22000條，為了方便觀察，也有可控制前端軸轉向變換不同視角的二方向及四方向控制機種。

The flexible small diameter flexible tube endoscope can deeply inspect the places that hard tube industrial endoscope can't reach. It is different from hard tube industrial endoscope in that it uses soft optical fiber to form image transmission system. Once the light enters the optical fiber, it can't escape, so the image transmission will not be affected by the rotation or bending of the endoscope axis; Since the image is composed of "points" with the same number of optical fibers, the image resolution is determined by the number of optical fibers; The more the diameter of the smaller fiber, the higher the imaging resolution, of course, the manufacturing cost will increase. The number of optical fibers of the windable industrial endoscope can be up to 22000 from 3500. For the convenience of observation, there are also two and four direction control models that can control the front-end shaft to change different viewing angles.

影像工業內視鏡為使用小于1/6"的感光芯片位于內視鏡軸端直接取像，經訊號傳輸線傳送至監視器顯像，因影像直接轉成電氣訊號所以內視鏡無法直接目視，照明采用LED位于軸端直接照明;優點為制造成本相對較低且與軸長無關，以屏幕觀察輕松容易，能儲存照片、錄像為離線分析作依據;缺點為受限于感光芯片位于軸端，內視鏡軸徑采用1/18”感光芯片較小只能達5.5mm(保證耐10m水壓并集成高亮度 LED燈)左右，如適當降低可靠性要求，可以做到3.8mm。另外耐環境性較差，容許耐溫性及耐震性均不及光學視內視鏡，無法應用于各種場合。

The image industrial endoscope uses a photosensitive chip less than 1 / 6 "which is located at the shaft end of the endoscope to take the image directly and transmit it to the monitor for imaging through the signal transmission line. Because the image is directly converted into an electrical signal, the endoscope can not be viewed directly, and the LED is used for direct lighting at the shaft end; The advantages are that the manufacturing cost is relatively low and has nothing to do with the shaft length, the screen observation is easy, and the photos and videos can be stored as the basis for offline analysis; The disadvantage is that the sensitive chip is located at the shaft end, the shaft diameter of the endoscope is 1 / 18 ", and the sensitive chip is small, which can only reach about 5.5mm (it can withstand 10m water pressure and integrate high brightness LED light). If the reliability requirements are properly reduced, it can achieve 3.8mm. In addition, the environmental resistance is poor, the allowable temperature resistance and shock resistance are not as good as the optical endoscope, so it can not be used in various occasions.
