Fiber Optic Sensor News 2
The application of fiber optic sensors in the security field is mainly in the following three aspects:
Perimeter security monitoring system
Important facilities such as military bases, nuclear power plants, and border lines are usually located in harsh environments with complex climatic conditions. At the same time, the perimeter safety of these facilities is relatively high, and the infrastructure of these places is relatively poor, even without the conditions of wild power supply. This puts higher demands on the perimeter security system. The fiber perimeter safety monitoring system has an outdoor passive monitoring system, which can be installed in the monitoring room, and transmits the vibration information received by the sensing cable to the monitoring center through the guiding optical cable. All the outdoor devices are passive devices, no need for the field. Power supply provides effective perimeter security monitoring.
Pipeline safety monitoring system
Pipeline safety monitoring is an arduous and complicated task, and pipelines are damaged due to improper construction, causing major pollution and economic losses. The conventional testing method is to send personnel to inspect along the pipeline, and some traditional monitoring methods are used, but the practice has proved that the effect is limited. The fiber-optic pipeline safety monitoring system can effectively solve the above problems, embed the sensor cable along the pipeline, feel the vibration around the pipeline through the fiber, and transmit this information to the monitoring host for analysis and judgment, eliminate the general interference, and finally generate an alarm. Inform the person on duty that the pipeline has an accident. The system is particularly suitable for the safety monitoring of oil pipelines in chemical plants and large oil depots, as well as the safety monitoring of natural gas pipelines, power lines and drinking water pipelines in large community municipal facilities.
Backbone cable security monitoring system
The backbone optical cable is the basis and important channel of modern communication. The security of optical cable operation and the security of information content are related to the national economy and national security. Therefore, the safety monitoring of backbone optical cables is very important. Although the optical time domain reflectometer (OTDR) can detect the optical fiber, it also has limitations. There is a blind zone and it cannot be monitored in real time. Especially through high-tech means, it can be unknowingly stolen without breaking the fiber. The information transmitted in the fiber, but the traditional monitoring methods can not be found. The fiber optic backbone cable security monitoring system monitors the entire fiber optic cable by accessing the fiber in the cable shaft. When a criminal suspects attempt to steal information inside the optical cable and touches the optical cable, the system immediately generates an alarm, which can effectively ensure the information security of the backbone optical cable. The system is particularly suitable for government buildings, military agencies, banks, as well as confidential and communications departments to monitor the safety of backbone optical cables.

According to the principle, the fiber optic gyroscope can be divided into interference type, resonance type and Brillouin type. This is the first generation interferometric fiber optic gyroscope of the third generation fiber optic gyroscope. At present, this technology is mature and suitable for mass production and commercialization; the second generation The resonant fiber optic gyroscope is still in the development stage of laboratory research to practical use; the third generation Brillouin type is still in the theoretical research stage.
Proximity Sensor News
What does the proximity sensor bring to our lives? In terms of basic research, proximity sensors have a more prominent position. The development of modern science and technology has entered many new fields: for example, macroscopic observations for thousands of years in the vast universe, microscopic observation of the world of FM particles, vertical observation of centuries of celestial evolution and short-term transient response . Let's take a look at what the Shenwu proximity sensor brings to our lives.
