摘要
菲涅尔透镜列阵,具有易阵列化的优点。设计中心波长相同的透镜列阵和中心波长不 同的透镜列阵,并对由此列阵构成的准直器的光束耦合特征进行分析和计算,与通用的准直器的相关参数进行比较,表明菲涅尔透镜列阵在光束准直耦合中具有较高的耦合效率,可以用于制作阵列光纤准直器。
Fresnel lens array has the advantage of forming an array. The lens array with same central wa- velength and the lens array with different central wavelengths are designed. The beam coupling characteristics of the collimator constituted by these arrays are analyzed and calculated. Compared with the related parameters of the common collimator, the results show that Fresnel lens array in beam collimating and coupling has a higher coupling efficiency and can be applied to manufacturing optic fiber collimator.
