本文报道了一种适合于形状传感的完整集成光纤组件的开发。我们的形状传感器模块由一根长度为100米的多芯扭曲光纤组成，光纤布拉格光栅沿其长度内嵌。我们的光纤具有紧凑的180微米涂层直径，每米扭转50转，光栅反射率每厘米阵列大于0.01%，适合在许多米长的光纤上进行高效散射测量。阵列末端采用单核到多核扇出和低反射率光纤终端。
In this paper we report on the development of a complete integrated optical fiber assembly suitable for shape sensing. Our shape sensor module consists of a length (>1m) of twisted multicore optical fiber with fiber Bragg gratings inscribed along its length. Our fiber has a compact 180 micron coated diameter, a twist of 50 turns per meter and grating reflectivities greater than 0.01% per cm of array, suitable for high efficiency scatter measurements over many meters of fiber. Single core to multicore fanouts and low reflectivity fiber termination are used to terminate the end of the array.
