摘 要: 对测量液体浓度用的各种不同形状的大直径玻璃光波导进行了研究,理论计算了其测量灵敏度与弯曲半径的关系,并建立了近红外的测试系统,对各种弯曲的光波导进行了测量,得到与理论分析相近的结果。 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.
