China Aerospace Science and Technology Spaceborne Fiber Bragg Grating Sensing System Accepts Acceptance

[China Instrument Network Instrument R&D] A few days ago, the satellite-borne fiber grating sensor system developed by 13 institutes of the 9th China Aerospace Science and Technology Corporation passed the project evaluation summary review.

It is reported that the fiber grating sensor in the spaceborne fiber grating sensor system is a kind of fiber optic sensor. The sensing process based on the fiber grating is based on the external physical parameters of the fiber Bragg wavelength. Modulation to obtain sensor information is a wavelength modulated optical fiber sensor.
In addition, FBG sensors can directly measure physical quantities such as temperature and strain. These sensors mainly include fiber grating strain sensors, temperature sensors, acceleration sensors, displacement sensors, pressure sensors, flow sensors, and liquid level sensors.
In addition, the review experts agreed that on-orbit test data proves that the 13-fiber-optic grating sensor system developed meets the test success criteria and the success of the deployment.
At the same time, the review experts fully affirmed the accuracy, stability and reliability of on-orbit measurement of FBG sensing systems, and it is recommended that they be popularized and applied in satellite temperature measurement.
The FBG sensing system developed by 13 has measured the temperature and strain inside and outside of the satellite cabin while the satellite is in orbit. This is the first time that the fiber grating sensing system has successfully mounted on satellites in China. The comprehensive performance indicators have been obtained. Full validation of the track environment.
