FBG Sensing Technology for Strain Monitoring of Rockets and Missiles in Defense Industry
Rockets and missiles are critical components of a nation's defense system, and their structural health monitoring is essential to ensure their optimal performance. One of the most important aspects of monitoring rocket and missile health is strain detection. Strain monitoring is essential in predicting and preventing structural failures and identifying potential performance issues. Fiber grating sensing technology is a reliable and accurate method for strain monitoring in rockets and missiles.
In this article, we will discuss the application of fiber grating sensing technology in strain monitoring of rockets and missiles in the defense industry，the principles of fiber Bragg grating strain sensing，the challenges faced in rocket and missile strain monitoring，and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the strain monitoring in defense industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Challenges in Rocket and Missile Strain Monitoring in the Defense Industry:
The harsh operating conditions of rockets and missiles make it challenging to monitor their structural health accurately. The high accelerations, temperatures, and vibrations experienced during launch and flight can cause significant strain on the structures.
Additionally, the limited space and weight constraints of rockets and missiles require sensors that are small, lightweight, and capable of operating in high-temperature environments. The sensors must also be highly reliable and accurate to ensure the safety and effectiveness of the rocket or missile.
What Strain Monitoring Problems Can FBG Sensing Technology Solve:
Fiber grating sensing technology can solve many of the challenges faced in rocket and missile strain monitoring. FBG sensors are small, lightweight, and capable of operating in high-temperature environments, making them ideal for use in rockets and missiles. They are also highly accurate and reliable, providing precise measurements of strain.
In addition, FBG sensors are immune to electromagnetic interference and do not require any electrical power, making them ideal for use in explosive environments.
