摘　　要：对自制特种液芯光纤进行了几何参数(直径)的检测,提出了一种基于数字图像处理的高效、实用的分析方法来测量光纤的直径.通过承载性能实验,测试了石英光纤、塑料光纤和特种液芯光纤的承载性能.结果表明,液芯光纤对外界的承载变化比较敏感,有较好的光强传感性能,具有和普通光纤相似的性质.根据液芯光纤输出光强的变化,可以判断其承载的大小,其承载能力比石英光纤和塑料光纤好.The geometrical parameter （diameter） of a self-made special liquid core optical fiber was measured with an efficient and practical method which was based on digital image processing. The load performance of quartz optical fiber, plastic optical fiber and special liquid core optical fiber was tested. The experimental results showed that the special liquid core optical fiber is more sensitive to the change of outside load and has better sensoring performance and similar property with general optical fiber. The load value can be calculated from the output intensity of the optical fiber. And the load performance of special liquid core optical fiber is better than that of the quartz optical fiber and the plastic optical fiber.
