Industrial optical fiber endoscope is a kind of remote visual inspection equipment, with fine diameter, flexible characteristics, mostly used for some narrow curved test piece internal inspection, such as: turbine, small diameter process pipeline, aircraft fuselage, boiler pipeline maintenance, easy to use, is widely used. Understanding the imaging principles of industrial fiber optic endoscope can help to buy good products. Industrial fiber optic endoscopes often consof the objective lens, the mirror tube, the control unit, and the eyepiece. The guide beam providing lighting and the guide fiber optic beam responsible for transmission are all running through the mirror tube. The imaging core of optical fiber mirror lies in the optical fiber beam, and its imaging principle can be understood from the perspective of local single optical fiber and overall optical beam. The imaging principle of industrial fiber optic endoscopy is based on a combination of optical and fiber optic technology, which allows the transmission of images through optical fibers, enabling visual detection in environments that are difficult to observe directly. This technology is widely used in aviation, automobile, electric power, chemical industry and other fields, providing a convenient and efficient means for the internal detection and maintenance of industrial equipment. First, let's take a look at the basic structure and characteristics of the optical fiber. The optical fiber consists of three parts: fiber core, cladding and coating. The core is the core part of the optical fiber that transmits the optical signal; the cladding protects the optical signal and prevents its leakage; the coating is the outermost protective layer, increasing the durability and flexibility of the fiber. The characteristics of optical fiber include low loss, high bandwidth, and strong anti-interference ability, which makes optical fiber an ideal choice for long-distance, high-speed, and large-capacity data transmission. In industrial optical fiber endoscopes, optical fibers are used to transmit light signals reflected back from the inside of the device. The probe portion of the endoscope is usually equipped with one or more fiber beams that introduce light signals from the external light source into the device and collect light signals reflected back from the inside of the device. These optical signals are transmitted to the viewing end through the fiber beam, which is then converted into a visual image through the imaging system. At the core of the imaging system is the image sensor, which converts the received optical signal into an electrical signal, which is then processed through an electronic amplifier and finally output to the display. Depending on the type of sensor, the imaging system can be divided into two types: a charge-coupled device (CCD) sensor, and the other is a complementary metal oxide semiconductor (CMOS) sensor. Both sensors have advantages and disadvantages, but both achieve high-quality image output. In addition to the imaging system, industrial fiber-optic endoscopes require an optical system to focus and adjust the light. The optical system includes components such as an objective, an eyepiece and a focusing mechanism, which together ensure that the light can be accurately focused on the sensor to obtain a clear, accurate image. In practical application, industrial optical fiber optic endoscope also needs to consider the influence of environmental factors. For example, the imaging quality of an endoscope may be affected in harsh environments such as high temperature, high humidity, and strong electromagnetic interference. Therefore, the design needs to take the corresponding protective measures, such as the use of high temperature, moisture, anti-interference optical fiber and sensors, to ensure that the endoscope can work normally in various environments. In addition, the industrial fiber-optic endoscope also needs to consider the problem of image processing. Because the transmission process may be affected by noise, distortion and other factors, it is necessary to pre-processing, enhancement and recovery of the received images to improve the clarity and contrast of the image. These image processing technologies include filtering, denoising, enhancement, segmentation, which can help us to better identify and analyze the information in the image. In conclusion, the imaging principle of industrial fiber optic endoscope is based on the combination of optical and fiber optic technology, through which images are transmitted through optical fibers and processed by the imaging system to obtain visual images. In practical applications, the influence of environmental factors and the problem of image processing are considered to ensure that the endoscope works properly and output high-quality images. With the continuous development of technology, industrial fiber optic endoscope will be applied and promoted in more fields.

Read MoreFiber optic is a slender light-conducting material made of high-purity glass or plastic that enables the transmission of light through internal reflection. In fiber optic transmission, light typically propagates along a straight path, but a series of optical phenomena occur when the fiber optic bends. Addressing fiber optic bending issues involves considering the following aspects: Choosing the appropriate type of fiber optic: When designing and installing a fiber optic network, it is possible to select fiber optic types that are suitable for bending. Flexible fiber optics usually have higher bend tolerance, allowing them to work on smaller radius curves without causing light loss. Therefore, choosing flexible fiber optic is an important step in reducing fiber optic bending issues. Controlling the fiber optic's bending radius: By controlling the bending radius of the fiber optic, it is possible to minimize bending loss. Generally, the larger the bending radius of the fiber optic, the lower the bending loss. During fiber optic cabling and installation, it is necessary to avoid excessive bending, particularly when the bending radius is smaller than the fiber optic's allowed bending radius. Proper equipment and techniques can be used, such as fiber optic bend protection sleeves and fiber optic strain relief devices, to ensure the fiber optic's bending radius is appropriate. Avoiding mechanical stress: Fiber optics are prone to mechanical stress in applications, such as tension, pressure, and twisting. These mechanical stresses can cause bending deformation and damage to the fiber optics, resulting in loss of light transmission. Therefore, during fiber optic cabling and installation, it is important to avoid applying mechanical stress and use suitable fiber optic protection devices and brackets to reduce the impact of mechanical stress on the fiber optic. Nanjing Hecho supports custom fiber optics, and by selecting the appropriate fiber optic type and controlling the fiber optic's bending radius, it is possible to effectively address fiber optic bending issues, improving the reliability and performance of fiber optic transmission, and meeting different customer usage requirements.

Read MoreIn environments above 400°C, organic materials used for coatings quickly undergo thermal oxidation aging, resulting in the loss of protection for the fiber and rendering it unusable. To enable normal operation at higher temperatures, high-temperature resistant metal materials (aluminum/copper/gold) are tightly wrapped around the bare fiber. Benefits of using high-temperature resistant metals: Lower coefficient of thermal expansion (similar to the fiber's coefficient) Corrosion resistance Good fatigue resistance, water resistance, and hydrogen resistance High mechanical strength Extreme high and low-temperature adaptability Weldability Using aluminum extends the temperature range from -269°C to +400°C, while copper extends it from -269°C to +600°C. Gold can withstand temperatures from -269°C to +700°C. This type of fiber is used for ultra-longevity in harsh external environments and can also be used as components in electronic circuits. However, due to its complex manufacturing process and high cost, it is often only used in short segments where necessary. Note: The metal coating process is complex and has very low production efficiency. Stripping the metal coating cannot be done with wire strippers and requires methods such as heat-sulfuric acid fusion or nitric acid for stripping. The introduction above covers the three types of fiber metal coating materials. Quartz fiber is widely used in communication and non-communication fields due to its wide spectral range and low loss. However, it is necessary to select fibers with different coating materials based on the requirements of different applications, environments, and sectors.
Read MoreFiber doping techniques involve introducing specific materials, known as dopants, into the core of the fiber to modify its optical and conduction properties. This technique finds wide applications in fields such as fiber optic communications, fiber sensing, and fiber lasers. Here are some common fiber doping techniques: Rare-Earth Ion Doping: Rare-earth ions (such as erbium, neodymium, and terbium) are commonly used as doping agents in optical fibers. By introducing rare-earth ions into the fiber core, functionalities such as amplification, laser emission, and frequency conversion can be achieved within specific wavelength ranges. Rare-earth ion doping is crucial for improving the performance of fiber amplifiers and fiber lasers. Doping via Solution Soaking: This method involves dissolving the dopant material in an appropriate solvent and immersing the fiber into the solution, allowing the dopant to permeate the fiber core. Subsequently, heat treatment is applied to solidify the dopant within the fiber. This method enables localized doping of the fiber and allows control over the dopant concentration distribution. Vapor Phase Doping: This technique utilizes chemical vapor deposition during the fiber manufacturing process to introduce the dopant. Typically, the dopant material and the fiber's raw materials are simultaneously introduced into a reaction vessel. Through chemical reactions like thermal decomposition or desorption, the dopant reacts and adsorbs onto the fiber core, resulting in doped fiber formation. Ion Exchange Doping: In this method, ions are doped into the fiber core through ion exchange reactions. Typically, the fiber core material is silica (SiO2), while the dopant solution contains the desired ions. During the ion exchange process, the silicon ions in the fiber core are replaced by the dopant ions, thereby achieving doping. Through doping techniques, specific optical, conduction, or excitation characteristics can be imparted to fibers to meet various application requirements. The development of these techniques continually drives advancements in fiber optic communication and fiber technology.
