Abstract

The scattering properties of an optical fiber with a silica light-conducting core and a light-reflecting shell made of a fluorinated thermoplastic copolymer of tetrafluoroethylene with Tefzel ethylene have been experimentally studied. It is established that when radiation (λ = 532 nm) propagates along this fiber, a noticeable scattering of the evanescent part of the wave propagating along the reflective shell is observed. The shell scattering indicatrix, the distribution of the scattered radiation intensity along the fiber axis, and its dependence on the conditions of radiation input into the optical fiber were measured. The total scattered radiation is calculated and compared with the radiation transmitted through an optical fiber. The possibility of using these optical fibers in laser medicine is discussed.

由氟化热塑性聚合物制成的具有二氧化硅光导芯和光反射壳的光纤的散射特性

摘要

实验研究了具有二氧化硅光导芯和由四氟乙烯与聚四氟乙烯的氟化热塑性共聚物制成的光反射壳的光纤的散射特性。可以确定的是，当辐射（λ= 532 nm）沿着该光纤传播时，观察到沿反射壳传播的波的渐逝部分的明显散射。测量了壳散射指标，沿纤维轴的散射辐射强度分布及其对输入到光纤中辐射条件的依赖性。计算总散射辐射，并将其与通过光纤传输的辐射进行比较。讨论了在激光医学中使用这些光纤的可能性。
