摘要
采用二种方式推算了光纤采用六边形排列配用圆形端套光纤传光束的理论敛集率,其值为90.69%,这一值同光纤采用六边形排列配用长方形端套的传光束理论敛集率一致.而单根粗直径聚合物光纤和液芯光纤配用圆形端套制作的光纤传光束,其敛集率为100%,在可见光或紫外光范围内,选用单根粗直径聚合物光纤或液芯光纤传光束具有更多的优势.分析了皮层的厚度对光纤传光束或传像束填充率的影响,当光纤半径低于250μm时,皮层厚度对细直径光纤传光束或传像束填充率影响明显,而当光纤半径大于等于500μm,皮层厚度的影响相对较小.
The theoretical packing fraction of the bundle of optical fibers which are arrayed in hexagon with round end-tip is calculated by two methods,and the value of packing fraction was 90.69% which was the same as the value of bundle of optical fibers that were arrayed in hexagon with rectangle end-tip. When an optical fiber bundle was made of a large-core polymer optical fiber or a liquid-core optical fiber,the value of packing fraction was 100~. In the range of visible light or ultraviolet light,it is much more advantageous to choose an optical fiber bundle made of a large-core polymer optical fiber or a liquid-core optical fiber. The influence of the thickness of the clad on the packing efficiency of the optical fiber bundle or fiber image bundle is analysed. The influence of thickness of clad on the packing efficiency was relative high when the radius of optical fiber was less than 250 μm. When the radius of optical fiber was more than 500 μm,the influence of the thickness of clad on the packing efficiency is relative low.
