提出了一种基于受激布里渊散射的单双通带可切换的微波光子滤波器。通过改变抽运光与信号光两波长之间的间隔,可实现单通带滤波器与双通带滤波器之间的切换,且通带频率可调。建立了理论模型并进行了仿真分析,并通过实验进行了验证。实验结果显示,抑制比达30 dB,0~18 GHz范围内的频率响应可调,实验结果与模拟结果相吻合。

We present a method that accurately measures large optical surfaces before polishing using a laser tracker. Using the scanning mode of the laser tracker considerably improves measurement efficiency and minimizes the dominant errors caused by environmental
In the context of nonlinear plasmonics, we review the recently introduced concept of plasmonic parametric resonance (PPR) and discuss potential applications of such phenomena. PPR arises from the temporal modulation of one or more of the parameters govern
Dynamic control of compact chip-scale contactless manipulation of particles for bioscience applications remains a challenging endeavor, which is restrained by the balance between trapping efficiency and scalable apparatus. Metasurfaces offer the implement

The spatial-intensity profile of light reflected during the interaction of an intense laser pulse with a microstructured target is investigated experimentally and the potential to apply this as a diagnostic of the interaction physics is explored numerical
To cope with the occlusion and intersection between targets and the environment, location prediction is employed in the visual tracking system. Target trace is fitted by sliding subsection polynomials based on least absolute deviation (LAD) estimation, an
分析了微分滤波对联合变换功率谱的影响,得到了一种称之为功率谱形式的微分滤波器。该滤波器的滤波函数为一实数并且有一定的特点,因此很容易制得。计算机模拟表明,功率谱微分滤波联合变换相关器在相关峰值、旁瓣比、半宽度等方面比一般联合变换相关器有显著的改善,可以大大提高相关图像识别的可靠性。文中给出了实验结果,与模拟计算结果吻合,引入一个新参数可以更好地描述相关图像识别中的相关性。
