基于锥形光纤制造过程的复杂性及其传像束的传输性能,利用微机与步进电机相结合,同时控制常用的双坩埚光纤拉丝机出丝管口的直径大小和鼓轮转速快慢,实现了数控拉制1 m长锥形光纤的新方法,并且集束制作出了两种两端不同半径比的锥形光纤传像束.与常用的增大鼓轮体积的方法相比,该装置具有体积小,便于操作,两端半径比可自由控制,断丝率低等特点.分析了这两种锥形光纤传像束的模式损耗.

Based on the complexity of fabricating the taper fiber and the performance in transmission of the image bundles,through applying the technology of combining step motor and computer,controlling the usual optical fiber double crucibles drawbench out-nozzle diameter and tub wheel′s rotating speed at the same time,of a way fabricating the taper fiber with numerical control,whose length can reach to 1m,is realized.Two image taper fiber bundles with the different ratio of radius are made.Compared with the ususl way that enlarging the volume of the tub wheel,this technique is smaller in the volume,easier to manipulate,easier to control the ratio of radius,more endurable to strain.At last we analyses the mode wastage of the taper fiber.
