：

为了提高大视场摄影测量系统的测量精度和稳定性,提出一种基于局部迭代搜索算法的相机相对定向方法,仅需要两幅图像间匹配的像面坐标信息,就可以计算相机之间精确的相对外方位参数。通过闭环多项式解法获得两图像之间本质矩阵的初值;将本质矩阵进行局部迭代,计算正交矩阵和外极线约束误差方程;利用两图像上所有匹配点的像面坐标,通过多次迭代获得本质矩阵的全局最优解;分解本质矩阵获得图像之间的相对外方位参数,并结合Ch

Optical investigations reveal the effects of 2-aminoethyldiphenyl borate on STIM1 puncta formation

2-Aminoethyldiphenyl borate (2-APB) is the most commonly used pharmacological agent in the study of calcium release-activated channels (CRACs); however, its inhibitory mechanism to CRACs remains unclear. To address this issue, we systematically employed c

Ef fect of optical losses on the transmission performance of a radio-over-fiber distributed antenna

The effects of optical losses on a directly-modulated radio-over-fiber (RoF) system used for distributed antenna networks are determined. The results show that with a properly designed bidirectional amplifier, the RoF link can tolerate over 20 and 16 dB o
