Manufacturer of Distributed Fiber Optic Vibration Sensing System (증권 시세 표시기) products

The invention of optical fiber has a history of nearly a century. The early stages of optical fiber had great losses, which limited its application. In the 1960s, under the promotion of Gao Kun and others, Corning Corporation in the United States first manufactured optical fibers with losses as low as 20 dB/km, making long-distance optical signal transmission possible, promoting the practicality of optical fiber communication and the development of related industries. The development of optical fiber communication also greatly promoted the development of software and hardware, including various optical devices and demodulation algorithms. On this basis, it was found that using changes in optical signals can be used to detect various physical parameters (such as temperature, magnetic field, angular velocity, 등.). Common optical signal characteristics include light intensity, frequency, phase, polarization state, 등. Compared with other types of sensors, optical fiber sensors have a series of advantages. 장점, including size, weight, tolerance to harsh environments, 등, 그러므로, it has been widely applied and has become a huge emerging industry.

분산형 광섬유 vibration sensing system (증권 시세 표시기) is based on the optical time-domain reflection (증권 시세 표시기) technology with phase information, using G652 single-mode fiber as the sensing medium. The laser emits a narrow linewidth pulse laser that is transmitted along the sensing fiber, while continuously generating backward Rayleigh scattered light, which undergoes multi beam interference. When the sensing fiber is subjected to external vibration interference, the phase of the backscattered Rayleigh light will change, causing a change in the intensity distribution of multi beam interference. The photoelectric conversion device detects changes in the intensity distribution of these interference lights and demodulates them into vibration signals. This is why DVS can detect external vibrations.
