Structural strain mapping using a wavelength/time division addressed fiber Bragg grating array
暂无分享,去创建一个
We describe a multiplexed nine element Bragg grating array used for strain mapping over a plate which is subjected to deflection forces. The system comprises two sub arrays of gratings which are sequentially addressed, and read via a single interrogation system into a PC. Real time strain distributions of the plate are determined and displayed.
