FBG Sensing Technology for Ship Structural Health Monitoring in the Defense Industry
Fiber grating sensing technology is a powerful tool that has revolutionized the way structural health monitoring is conducted in the defense industry. With the ability to detect changes in temperature, strain, stress, displacement, vibration, and shape, fiber grating sensors provide valuable insight into the health of ship structures. This technology is particularly useful in detecting early warning signs of structural damage, which is critical to ensuring the safety and reliability of military vessels.
As the defense industry relies on advanced technology to ensure the safety and reliability of ships, fiber grating sensing technology has become a critical tool for the health detection of ship structures. By providing high accuracy and sensitivity, fiber grating sensors can detect changes in strain, temperature, and vibration, which can help predict potential failures before they occur. In this article, we will discuss the problems that fiber grating sensing technology can solve，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the strain monitoring in aerospace industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg grating (FBG) sensors are a type of fiber optic sensor that uses a special type of grating to reflect a narrow wavelength of light back along the fiber. When the fiber is subjected to changes in strain, temperature, or other physical parameters, the reflected wavelength changes, providing an accurate measurement of the physical parameter being monitored. This principle is based on the fact that the spacing between the grating planes in the fiber changes with the physical parameter being monitored. By analyzing the reflected wavelength of light, the physical parameter can be accurately measured.

Challenges in the Health Monitoring of Ship Structures in the Defense Industry:
In the defense industry, the health monitoring of ship structures is a critical component of ensuring the safety and reliability of military vessels. However, there are several challenges associated with this task, including the harsh operating conditions that ships are exposed to. For example, the corrosive effects of seawater can cause significant damage to the metal components of a ship, leading to structural damage and failure. In addition, ships are subject to significant stresses and vibrations during operation, which can also cause structural damage.
What Problems Can be Solved by FBG Sensing Technology:
Fiber grating sensing technology can help overcome many of the challenges associated with ship structure health monitoring in the defense industry. By providing high accuracy and sensitivity, FBG sensors can detect changes in strain, temperature, and vibration, which can help predict potential failures before they occur. This technology can also be used to detect and locate structural damage, enabling timely repairs to be made before the damage becomes more severe. Additionally, the small size and flexibility of FBG sensors make them easy to install in a wide range of ship structures, making them a valuable tool for comprehensive health monitoring.
