STUDY OF THE METHOD FOR MEASURING LIQUID DENSITY BY OPTICAL WAVEGUIDE
液体浓度光波导测量方法研究

The investigation of optical glass waveguides for liquid density measurement with large diameters in various shapes is reported. The dependence of sensitivity on the bending radius was calculated. The measurement system in the near infrared waveband was set up. Various bending waveguides were measured, and the results of measurement are nearly in agreement with the theoretical analysis.
