传能光纤和光电池耦合系统的设计与研究

Design and research on the coupling system between power-transmitting fiber and photovoltaic cells

采用横向偏移法测试传能光纤出射光束的光强分布。仿真了单独使用平凹透镜的系统和将透镜与椭球面配合使用的系统,并对仿真结果进行对比分析。运用高斯光束复参数分析法对未到达椭球面的近轴光束进行光学分析。在耦合系统光路设计的基础上,进行了光电池选取与结构设计。

The paper uses a method of transverse offset to measure the intensity distribution of transmitted beam of power-transmitting fiber. It makes a simulation between a coupling system which is only with a plane and concave lens and another system of lens as well as a ellipsoidal surface, and make a contrast of the results. The paper applies the complex parameter analysis method of Gaussian beam to take a analysis for the paraxial beam which is not arriving the ellipsoidal surface. On the basis of light path design of the coupling system, the paper chooses the photovoltaic cells and designs the structure.
