New or optimized-mixed evaporation materials of PIZOLIN, ALVIRIT, ROMA, and TiO53[1] on the basis of high-index pure substances of TiO2, Nb2O5, CeO2, ZrO2, and Ta2O5 are developed with the aim of identifying dielectric materials with specific refractive indices, reduced film stress, better wear or humidity resistance, and improved ultraviolet (UV) blockage compared to pure substances. Materials are tested in conventional and slightly ion-assisted deposition using process windows typical for coating polymeric substrates. Films with refractive indices in the range of 2.08–2.40, as well as tunable film stress below values for pure substances, are observed. In some cases, the admixture leads to a shift in absorption edge or improvement in moisture resistance of films. Individual results based on the new formulation on film materials with blue colour in transmission (OLIVIN P) in metal and metal oxide mixtures are presented.

We propose and demonstrate a simple configuration of wavelength-tunable fiber laser made up of a tunable band-pass filter, a Sagnac loop reflector, and a Fabry-Perot laser diode. Based on the self-seeded operation, the proposed fiber laser can obtain a si
Color inconsistency is an urgent problem to be solved in free viewpoint television. In this letter, a new color correction method is proposed by using disparity vector information. At first, we separate foreground and background from the scene with a meth
In order to test convex aspheric surfaces without the aid of other null optics, a novel method combined sub-aperture stitching and interferometry called SSI (sub-aperture stitching interferometry) is introduced. In this letter, the theory, basic principle
Two-photon excited fluorescence materials usually suffer from inefficient two-photon absorption (TPA) and nonradiative excited states. Here, upconversion fluorescence in an electron donor-acceptor (DA) exciplex doped with fluorescent emitters are systemat

提出一种半主动寻的激光制导干涉编码方法, 在传统时序编码基础上加入多子光束相干发射系统产生的空间干涉图样, 形成时空域相融合的编码信号。设计一种多子光束相干发射系统, 依据子光束良好的空间相干性进行空间构图, 形成编码可控的空间干涉图样。计算结果表明: 当参数K值(子光束对角线之比)在2.5~3.5之间时, 干涉图样明暗相间程度最为明显, 干涉图样最为纯净; 当子光束相干发射系统中分束镜的位置偏移小于0.1 ?姿(?姿为激光波长), 角度偏离小于0.1 ?兹0(?兹0为光束发散角)时, 发射系统机械振动对
在制造磁光仪器时，将石榴石结构铁氧体磁性薄膜用作活性介质使人们产生很大的兴趣。在带有规则畴结构的磁性介质中传播偏振光时，磁畴中方向相反的磁矩将促使透过光辐射的偏振平面发生旋转。这样,被调制的光辐射将形成一个衍射图，它的参数可由磁矩在光线传播方向的投影符号和大小来确定。因此，对于光波来说，磁性晶体或薄膜就是二种按法拉第效应工作的位相衍射光栅。
针对机载合成孔径激光雷达实测数据成像中旁瓣较高的问题, 提出一种新旁瓣抑制算法。压缩感知理论表明, 稀疏信号恢复重构过程的同时, 信号旁瓣会被压低, 但合成孔径激光雷达图像不是稀疏的。针对这一问题, 提出了一种基于改进SVA(Spatially Variant Apodization)和压缩感知重构SAL图像的旁瓣抑制算法。首先, 利用改进SVA算法将SAL图像变稀疏, 然后再利用压缩感知算法对稀疏图像进行恢复。分别对SAL仿真数据和实际高旁瓣SAL复图像进行抑制旁瓣处理。仿真结果表明: 该算法能够在保证
