We present linear conjugated combined aberration modes with a concentric pupil diameter of 4 mm. The combinations are according to the coupling relationship between Zernike modes over the concentric circle domain within the unit circle and the root mean square decreasing amplitude ratio of the corresponding aberration modes in the concentric pupil, in which the reconstruction pupil diameter is 6 mm. Each combined mode shares the characters of 2 radial orders apart, the same azimuth frequency, the same coefficient sign, and the prescribed amount, such as (C02 = 0.7\lambda, C04 = 0.3\lambda), (C-33 = 0.8\lambda, C-35 = 0.3\lambda), and so on. We also analyze the influence of the combined modes on optical quality. Simulations and experiments show improvement after combination; they also indicate that the influence of conjugated combination on optical quality has compensation and not superposition.

The simultaneous dual-band pulsed amplification is demonstrated from an Er/Yb co-doped fiber (EYDF), and consequently a high-power all-fiber single-mode 1.0/1.5 μm dual-band pulsed master oscillator power amplifier (MOPA) laser source is realized for the
提出一种基于SKL (Symmetric Kullback-Leibler)散度的点集配准算法,将点集中的每一个点表示成一个高斯分布,高斯分布包含点的位置信息和周围点的影响大小信息。将整个点集建模为一个高斯混合模型(GMM),因此两点集的配准问题转化为求两GMM间SKL散度的最小值问题。采用遗传算法进行优化求解。实验结果表明,所提算法对噪声、出格点和缺失点具有较强的鲁棒性,且取得较高的配准精度。

分别采用超高速(50 m/min)和常规(1.5 m/min)熔覆速度,在调质处理的27SiMn液压支架基材上成功制备了431不锈钢耐蚀涂层,对比分析了两种方法制备涂层的宏观特征、显微组织及耐蚀性能。试验结果表明:两种方法制备的涂层均无微观裂纹与气孔缺陷,且与基体形成了良好的冶金结合;相比于常规激光熔覆涂层,超高速激光熔覆的涂层具有类似“多米诺骨牌”的多层重叠结构,稀释率仅为4%,涂层中Cr的原子数分数为19%;常规激光熔覆涂层组织整体较为粗大,在搭接位置由于温度梯度的改变,枝晶生长方向紊乱;超高速激光熔

p型单晶硅太阳电池在EL检测过程中, 部分电池片出现黑斑现象。结合X射线能谱分析(EDS), 对黑斑片与正常片进行对比分析, 发现黑斑片电池与正常电池片大部分表面的成分相同, 排除了镀膜及丝网印刷过程中产生黑斑的可能。利用X射线荧光光谱分析(XRF)测试了同一电池片的黑斑区域与正常区域, 发现黑斑处Ca含量较大, 并出现Sr、Ge和S等杂质元素。将6个档位的电池片制备成2cm×2cm的电池样片, 利用光生诱导电流测量了每个电池的外量子效率(EQE)。在460~1000nm波长范围内, 同一电池片黑斑处与正
