为了克服传统氙灯太阳模拟器成本高、寿命短、功耗大等缺点, 提高太阳电池测试的准确性, 本文首先设计了一种基于11种波段的LED太阳模拟器, 在光谱匹配度、不均匀度和不稳定度上均达到IEC60904-9-2007规定的A级标准。在此基础上, 开发了配套的太阳电池测试系统, 经过光源控制、数据处理、温度修正以及参数计算, 得到太阳电池的电特性参数。实验结果表明, 系统可以准确测得单晶硅太阳电池片的各项参数, 且结果稳定, 从而验证了光源的可靠性及测试方法的科学性。

利用滤波器原理从空间频域分析了连续镜面分立驱动变形镜对波前的补偿能力.将变形镜等效为一高通滤波器,通过数值计算分析了滤波器函数与驱动器密度、高斯指数、交连值等变形镜主要参数的关系,解释了参数变化对波前拟合能力的影响.结果表明:驱动器密度是波前补偿能力的决定因素,增大高斯指数和交连值一定程度上有利于低空间频率波前的补偿.应用中应该根据待补偿波前的特征正确地选择和调整变形镜参数.

In adaptive optics (AO) system, the phase compensation capability is limited greatly by the actuator number of the deformable mirror (DM). The actuator number of DM is mainly restricted by the manufacture techniques. The spatial correction capability of AO system can be improved by two or more combinational-DMs (CDMs) with conjugation relationship. The CDM AO system for wavefront correction is built, which consists of two 32-element DMs. The experimental results are in agreement with the numerical simulation results. It is indicated that the CDM AO system provides better correction performance than the single 32-element DM AO system.

A new kind of adaptive optics (AO) system, in which several low spatial frequency deformable mirrors (DMs) with optical conjugation relationship are combined to correct high-order aberrations, is proposed. The phase compensation principle and the control method of the combinational AO system are introduced. The numerical simulations for the AO system with two 60-element DMs are presented. The results indicate that the combinational DM in the AO system can correct different aberrations effectively as one single DM with more actuators, and there is no change of control method. This technique can be applied to a large telescope AO system to improve the spatial compensation capability for wavefront by using current DM.
