采用聚碳酸酯毛细管作为红外空芯光纤的基管材料,制作了内直径为320微米的细径红外空芯光纤.内面镀有光滑银膜的聚碳酸酯毛细管,在近红外和中远红外波段获得了平坦的损耗-波长响应特性.用224根镀银聚碳酸酯空芯光纤,制作了长度40mm,截面积约50m2的红外图像光纤束.利用该红外光纤束成功进行了加热电阻丝的红外热图像传输实验.红外聚碳酸酯空芯光纤束具有柔韧性强、无毒等特点,在医疗及工业领域有广阔的应用前景.
Using polycarbonate capillaries as the base material of the infrared hollow core optical fiber, a narrow-diameter infrared hollow-core optical fiber with an inner diameter of 320 micrometers was fabricated, and a polycarbonate capillary coated with a smooth silver film on the inner surface was obtained in the near-infrared and mid- A flat loss-wavelength response characteristic was obtained.The infrared image fiber bundles with a length of 40mm and a cross-sectional area of about 50m2 were fabricated by using 224 silver-plated polycarbonate hollow-core fibers.The infrared fiber bundles were successfully used to heat infrared Image transmission experiment. Infrared polycarbonate hollow fiber bundle has the advantages of flexibility, non-toxicity and so on. It has broad application prospects in medical and industrial fields.
