摘要 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. Hollow polycarbonate(PC) fiber with a small bore-size of 0. 32 mm was fabricated by using PC capillary as a supporting tube for infrared hollow fiber. The flat low-loss spectrum was attained from the near infrared to the far infrared wavelength regions by using hollow PC fiber inner-coated with a smooth silver film. Infrared fiber bundle was made by using 224 pieces of silver-coated hollow PC fiber with O. 32 mm bore-size. The length of the bundle is 40 cm and the cross sectional area is around 50 square centimeters. Thermal infrared image of a heated wire was successfully transmitted through the bundle. The flexible and non-toxic infrared fiber bundle is a promising transmission medium for applications in medical and industrial field.
