Detection and recognition of distributed optical fiber intrusion signal
Zhang Yongkang, Shang Ying, Wang Chen, Zhao Wen?an, Li Chang, Cao Bing, and Wang Chang
Distributed acoustic sensing (DAS) technology can detect acoustic or vibration signals with high sensitivity and wide dynamic range by receiving the phase information from coherent Rayleigh scattered light. Linear quantization is used to measure high fidelity restoration of the signals. With the increasing demand of pr

Respiratory rate monitoring system based on inorganic halide perovskite humidity sensor
Wu Yingjie, Wu Zhilin, Wang Lin, Nian Weiqi, He Yong, and Guo Yongcai
The traditional respiratory rate measurement technologies have several deficiencies, such as subjective appraised results, complicated signal extraction processes, difficult access to equipment, and inconvenience to move due to the wired connection setting. The respiratory airflow can directly reflect the human breath,

Embedded gold-plated fiber Bragg grating temperature and stress sensors encapsulated in capillary copper tube
Zhang Yanjun, Gao Haichuan, Zhang Longtu, Liu Qiang, and Fu Xinghu
In order to realize the non-destructive and real-time dynamic stress monitoring method of the construction machinery surface in complex and harsh environments, a fiber Bragg grating (FBG) stress sensor packaging method based on magnetron sputtering technology is proposed. Two packaging methods of complete embedding (th

Refractive index insensitive two parameter sensor based on dual mode LPEG
Wang Xiangyu, Qiao Xueguang, and Yu Dakuan
The variation of ambient refractive index and ambient temperature is the main factor affecting the error of optical fiber strain measurement. In this paper, a strain sensor based on the dual-mode fiber (DMF) long period fiber grating (LPFG) is designed. The sensor model structure was designed, and the sensor samples wi
