描述了用于激光等离子体软X射线光谱学研究的长波晶体谱仪。用具有大晶格常数的晶体(PHM,2d=6.35 nm),极薄的滤片和对软X射线灵敏的底片,获得了波长达5.8 nm的激光等离子体软X射线光谱。同时还给出了实验测定的谱仪光谱分辨率。

We propose a type of diffractive optical element, a modified Fibonacci photon sieve (MFiPS), designed by using the Fibonacci sequence with two different initial seed elements. Focusing properties of MFiPS show that it not only has less secondary foci, but

首先,利用透明物体表面反射光和透射光在垂直和平行方向上的光强分布关系,基于偏振正交分解原理,推导出反射光成分、透射光成分、反射光偏振度、透射光偏振度之间的函数关系。然后,根据相机成像原理,利用表面法向量求解得到透明物体表面不同位置处入射光线和法向量的夹角及入射面方位角,进而归纳出图像中各个像素点的反射光偏振度和透射光偏振度的分布规律。最后,基于反射和透射的偏振特性和相关特性,利用梯度下降算法计算得
Based on two-step coordinate transformation along the radial direction, an optical device with three functions is proposed. The proposed device functions as a transparent device, a vision-enabling internal cloak, and a movement-allowing external cloak. Th
以单光束偏振倍频理论为基础,研究了在手性实验装置中当起始入射光和倍频出射光的偏振态均为线性时,与p s偏振倍频光信号相关的非零实验展开系数f,g 和h 的唯一性。研究结果表明,对于具有D-π-A型结构的有机光学材料分子,当采用s和p±s等类型线偏振起始光时,实验拟合展开系数唯一,而p线偏振起始光情况的拟合系数却不唯一,相应p s线偏振倍频探测的模拟信号能够完全解释实验结果与早期理论预示之间的矛盾。为了精确确定D-π-A型结构材料的所有二阶非线性极化率张量元,在手性实验装置中避免使用p偏振起始光是非常有必要
