Young's modulus, as an important parameter in material mechanics, plays an important role in engineering design and teaching research. Fiber Bragg grating, as the most popular optical sensor device, has outstanding advantages such as high sensitivity and strong anti-interference. Therefore, this article uses 42CrMo alloy steel as the measurement material. A design method for measuring the Young's modulus of metallic materials using fiber Bragg gratings and pressure sensors is proposed. The Young's modulus of the metal to be tested is obtained through experiments. And compared with the Young's modulus of standard materials. The design method is simple and the measurement accuracy is high.

Remotely Optically Pumped Amplifier is an important form of the interference type optical fiber sensing remote relay transmission system. In this paper, the relationship between the nonlinear spontaneous Raman effect and the sensor phase noise in remotely pumped optical amplification is studied. The results show that in a 100km transmission system, with the increase of pump power the spontaneous Raman effect increases and a random fluctuation of pump optical power. The pump light fluctuation leads to the gain distortion and decrease of the remote gain unit, which ultimately transforms the pump intensity noise into the phase noise of the system. The experimental results show that when the pump power is controlled below 1.1W, the phase noise of the remotely pumped optical amplification system is at - 98dB@1kHz. And there are no obvious phase noise introduced into the remotely pump optical amplification system.

Multi-hop is a promising technology that can help the free space optical (FSO) transmission to establish robust routes in atmospheric turbulence. In this work, a multi-hop FSO communication system based on decode-and-forward protocol is investigated over $M$ distribution united with path loss and pointing errors. Particularly, with the BPSK subcarrier intensity modulation and direct detection techniques, the analytical expressions of average bit error rate and ergodic capacity are obtained for an independent but not identically distributed FSO system, and corroborated through Monte Carlo simulation method. Moreover, numerical analyses are presented to evaluate the influences of atmospheric turbulence, pointing errors and hop counts on performance of the studied system.

A two axes fiber optical gyroscope comprising a two loops structure (TLS) using a 3 × 3 coupler is presented. The length of the two loops is 2 m and 1.8 m. When one of the two axes is vertical to another, a dual-axis gyroscope comes into being. The phase difference between the counter-propagating waves in TLS is calculated and discussed. The sensitivity can be improved by adding a bias phase, but only if the phase difference is a monotonic function of the angular rate, with the best sensitivity obtained by adding a phase bias of ±3π/2.
