内窥镜工业探伤技术原理是什么?

来源:http://www.jiangrenyiliao.cn/ 发布时间:2021-07-05 浏览量:100

内窥镜除了大家了解的在医疗检查方面的应用,实际上现在在工业方面,有了更多的先进的管道内窥镜。
In addition to the application of endoscopy in medical examination, there are more advanced pipeline endoscopes in industry.
广泛的应用:
Wide range of applications:
从成像形式分为:硬管工业内视镜、软管工业内视镜镜、影像工业内视镜。硬管工业内视镜轴心装有许多消色差光学镜片组成影像传递系统,可以得到较高质量的影像,没有失真的传到检测者的眼睛,所以成像非常的保真,也是这几种镜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.

可绕式小直径软管内视镜可深入检查硬管工业内视镜无法到达的地方,它与硬式工业内视镜较大的差异为使用软性光学光纤组成影像传递系统,光线一旦进入光纤后即无法逃脱,因此内视镜轴扭转或弯曲均不会影响影像传递;由于影像是由与光纤数目相同的「点」组成,亦即影像分辨率由光纤数目所决定;越多直径越小的光纤其成像分辨率也越高,当然制造成本也随之提高。可绕式工业内视镜光纤数目可由3500条至高达22000条,为了方便观察,也有可控制前端轴转向变换不同视角的二方向及四方向控制机种。
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.
影像工业内视镜为使用小于1/6"的感光芯片位于内视镜轴端直接取像,经讯号传输线传送至监视器显像,因影像直接转成电气讯号所以内视镜无法直接目视,照明采用LED位于轴端直接照明;优点为制造成本相对较低且与轴长无关,以屏幕观察轻松容易,能储存照片、录像为离线分析作依据;缺点为受限于感光芯片位于轴端,内视镜轴径采用1/18”感光芯片较小只能达5.5mm(保证耐10m水压并集成高亮度 LED灯)左右,如适当降低可靠性要求,可以做到3.8mm。另外耐环境性较差,容许耐温性及耐震性均不及光学视内视镜,无法应用于各种场合。
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.
