Holmium laser is a pulsed laser with a wavelength of 2.1 μ m, which has strong safety and wide applicability compared with the commonly used extracorporeal shock wave lithotripsy and pneumatic ballistic lithotripsy. In the process of lithotripsy, stones rarely run, and the return rate is very low, so the efficiency is greatly improved. It can be directly crushed through cystoscopy, ureteroscopy and percutaneous nephroscopy, without causing tissue damage. And the holmium laser fiber is flexible, so it can effectively treat ureteric and kidney stones in any site.

The study shows that the single success rate of endoscopic holmium laser lithotripsy is more than 95%, and the treatment of bladder stones can reach 100%. The procedure is non-invasive or minimally invasive, and the patient is basically painless. There is no risk of perforation, bleeding, but also the combined treatment of urinary tract tumor, ureteral polyps, stricture and so on.

The specific process is soft ureteroscopic holmium laser lithotripsy is to use a fiber optic lens with about 3mm in diameter, inserted into the ureter through the urethra and bladder to the renal pelvis and renal calyx. Holmium laser fiber is used to remove and drain the upper ureteral stones and kidney stones. The use of human natural urinary tract, without making any incision in the body, is a pure urology cavity minimally invasive technique, so it is favored by patients.

The core technologies of machine vision include image acquisition, image pre-processing, feature extraction, target detection and recognition, etc. First, machine vision needs to obtain the image through devices such as cameras, and then preprocess the image, including denoising, enhancement, geometric correction, etc., to eliminate the interference and noise in the image.

Object detection and recognition is one of the important tasks of machine vision. By training models and using machine learning algorithms, machine vision can identify and locate target objects in the image, such as faces, vehicles, product defects, and so on. This provides very valuable applications for automated production, intelligent security and intelligent transportation.

The development of machine vision technology benefits from the improvement of computer computing power, the improvement of sensor technology and the development of artificial intelligence technology such as deep learning. These advances have led to significant improvements in accuracy, real-time, and adaptability.

The loss is mainly caused by the scattering and escape of light generated by the fiber during bending.

When the light is transmitted in a curved fiber, part of the light will escape from the fiber due to the changing propagation speed and direction of the light in the medium, thus causing the loss of the optical signal.

In addition, the propagation of light in the optical fiber is through full reflection, and at the bend, the degree of incidence angle of light may exceed the critical angle of full reflection, resulting in scattering phenomenon, which will also cause the loss of optical signal.

The size of the macrobending loss is affected by many factors, including the bending radius, the type and material of the fiber, and the outer coating of the fiber. A smaller bending radius will increase the scattering and escape of light, resulting in increased macrobending loss.

The special outer coating can reduce the scattering and escape of light, thus reducing the macrobending loss.

Optical fiber hydrophone system is a complex sensing system, which mainly uses optical fiber sensing technology to realize the conversion, transmission and processing of underwater sound signals. As the core part of the system, the implementation process are crucial to the performance of the whole system.

 The components of optical fiber hydrophone mainly include wet end and dry end. The wet end, as the sensing end, consists of the optical fiber hydrophone sensor probe and the transmission optical cable used to transmit the optical signal. The sensor probe is the core component of fiber-optic hydrophones, which can receive underwater sound signals and convert them into optical signals.

The dry end mainly includes the light source of optical fiber hydrophone, optical passive device, photoelectric conversion module and signal demodulation processing module. The light source is responsible for providing stable optical signals. The optical passive device is used to control the transmission and modulation of the optical signal. The photoelectric conversion module converts the received optical signal into an electrical signal, and the signal demodulation processing module demodulates and processes the electrical signals to extract useful sound information.

 With the continuous development of science and technology, the use of electric power electrical equipment safety has been constantly concerned. Optical fiber temperature measurement in the power system and oil and gas pipeline application range gradually into people's vision, but for the operation principle we know little, the following to introduce the principle of fluorescent fiber temperature measurement, distributed fiber temperature measurement principle, fiber grating temperature measurement principle. Optical fiber temperature measurement can not only be used in the field of electric power, petroleum and petrochemical, but also in the field of scientific research and experiment.

Based on the fluorescence lifetime of the temperature measurement of the optical fiber, generally speaking, the outer electrons of the fluorescent material molecules are in a relatively stable state, when the excited light is illuminated, the electron absorption energy transition will appear. After the excitation light disappears, it is allowed to return to the ground state, but the energy keeps radiating, creating fluorescence. For its specific temperature measurement, the temperature of the material surface is related to the decay of the fluorescence afterglow itself, and the so-called afterglow decay is actually the fluorescence lifetime. There is a direct relationship between the length of the fluorescence lifetime and the temperature. After the temperature of the fluorescent substance is determined, the actual afterglow retention time is the lifetime, which itself is monotonous with the current signal. Therefore, through the characteristic curve, the corresponding material can be selected as the probe, and through the relationship between the detected current value and the time stent, the surface temperature can be clearly defined, and then the temperature of the monitoring point can be determined. In the project implementation, compared with the normal operating temperature detection, the temperature after the failure increases abnormally, so the detection significance is greater.

Endoscope, an examination device that can directly enter the natural human cavity, provides doctors with sufficient diagnostic information to treat the disease. There are many kinds of endoscopy, including gastrointestinal endoscopy, thoracic laparoscopy, tracheoscopy, hysteroscopy, ureteroscopy, etc. Different kinds of endoscopes, applied in different departments. Gastroenterology department, cardiothoracic surgery department, urology department, gynecology department, respiratory department and other departments, all need to use medical endoscopy for diagnosis or treatment.

However, the traditional endoscope structure is complex and difficult to thoroughly clean and disinfect. The application of the same endoscope between different patients can easily lead to cross-infection, which can cause serious damage to the health of the infected person and even death.

After years of exploration by endoscope enterprises, the disposable endoscope is on the "stage". Its appearance effectively solves the problem of cross-infection, and there is no loss of endoscope for disposable use, which can ensure that each unpackaging endoscope is in the best state, and improve the surgical efficiency to a certain extent. In addition, disposable endoscopy can also enable hospitals to effectively control the cost related to endoscopy, and promote the promotion of endoscopic surgery in primary hospitals.

The clinical application of medical endoscopy technology mainly focuses on diagnosis and treatment. Through different mirror bodies, it provides good operating field and space for clinicians in various parts of the human body, which is convenient for clinicians to conduct minimally invasive diagnosis and minimally invasive treatment. Endoscopy technology brings operational space for minimally invasive treatment. Minimally invasive treatment will already become one of the important branches of future medical development.

Compared with traditional open surgery, minimally invasive surgery has the characteristics of less trauma, less bleeding and faster postoperative recovery. With the improvement of scientific and technological level, minimally invasive treatment techniques and related instruments have become more mature and reliable, and some minimally invasive surgery has become the first-line treatment plan in clinical medicine.

Usually a traditional endoscope host is about millions of yuan, soft mirror tens of thousands of yuan, plus maintenance costs, disinfection costs, human expenditure, the cost is not cheap, grass-roots institutions basically "can not afford to buy" also "can not afford to use".

The serious lack of endoscopic resources at the grassroots level is the vision of disposable endoscope entering the grassroots level to solve the lack of medical resources of the public. As an emerging force, disposable plastic endoscope can realize immediate examination, obtain information about patients' diseases and complications, and improve the level of primary medical services and the ability of patient management. Due to its convenience and low cost advantages, it is suitable for various primary medical institutions and doctors, which is helpful to achieve rapid diagnosis and treatment, screening and referral and diversion.

Distributed acoustic sensing (DAS) technology realizes the real-time monitoring of the optical cable or pipeline by using the backward Rayleigh scattering signal in the optical fiber. The technology is based on a phase-sensitive optical time domain reflector (Φ -OTDR) to reconstruct and detect events such as sound or vibration by detecting the backscattering signal generated when coherent pulse light propagating through the optical fiber.

 In the optical cable monitoring, the DAS system can accurately restore the sound information around the optical cable, such as vehicles, man-made damage, etc., and filter through the intelligent analysis function, interference signals, to ensure the accurate identification of events.

For pipeline monitoring, DAS technology can simultaneously measure various parameters, such as acoustics, temperature, pressure, strain and hole noise, and quickly and accurately detect and classify leakage events, third-party interference and other threats, providing a strong guarantee for the safe operation of the pipeline.
