聚焦纤维透镜已广泛应用于光电子技术成像领域。为快速计算其成像特性和绘制光路，基于MATLAB软件，编写了折射率呈抛物线形分布的聚焦纤维透镜成像模拟软件。在输入光纤和物体的基本参数后，软件可快速计算出光纤的特性常数和焦距以及像距、像高和线放大率，能准确绘制出成像光路图。该成果对光纤成像的研究和设计以及光电子技术课的教学均有较大的帮助。

Focusing fiber lenses are widely used in the photoelectronic imaging technique. In order to quickly calculate their imaging features and draw light paths, the imaging simulation software for those focusing fiber lenses with parabolic refractivity distribution is developed on the basis of MATLAB When the basic parameters of the fiber and object are input, the software can quickly calculate the fiber characteristic constant,focal length, image distance,image height and linear multiplying factor,and accurately draw the imaging light path. This work is conducive to the study and design of fiber imaging and to the teaching of photoelectronics techniques.
