The band-pass characteristic of fiber grating Michelson interferometer is analyzed, which acts as both band-pass filter and Q-switch. An erbium-doped fiber ring laser based on fiber grating Michelson interferometer is implemented for producing single longitudinal mode CW operation with 5 MHz spectral linewidth and up to 6 mW output power. In Q-switched operation, stable fiber laser output pulses with repetition rate of 800 Hz, pulse width of 0.6 μs, average power of 1.8 mW and peak power of 3.4 W are demonstrated. The peak power and average power of the Q-switched pulses are varied with the repetitionrate.

色散是光子晶体光纤最为重要的特征参量之一。在分析当前各数值计算方法特点的基础上，将最简单的经验公式法和基于多级法的光学系统超高节免设备(CUDOS)仿真软件结合起来，对全内反射型光子晶体光纤的色散特性进行了数值计算，分析了孔径d、孔间距Λ以及d/Λ对色散的影响，得到了一些对于光子晶体光纤的设计具有一定的指导意义的结论。同时，利用之前搭建的基于超连续谱白光干涉仪的超宽波段、高精度色散测量系统，对孔径d=2.17 μm、孔间距Λ=3.47 μm的全内反射型光子晶体光纤的色散系数进行了测量。实验结果与数值计算的
传统非局部均值(NLM)算法在滤波过程中采用固定滤波系数,从而导致图像细节过度平滑。为解决此问题,引入结构张量(ST)的迹作为图像特征区域的判别准则,设计了一种自适应滤波系数的权值函数(ST-NLM)。此外,针对传统算法计算耗时的问题,采用积分图像对算法进行加速。测试结果表明:经ST-NLM方法去噪后,图像整体平滑度和细节保留程度均较好;与NLM相比,ST-NLM方法的峰值信噪比提高了3 dB,结
针对激光散斑干涉图像在局部高密度噪声和拉线区域中,最小二乘解包裹算法存在过度平滑、迭代次数多和运行时间长等问题,提出一种新的算法。该算法基于散斑干涉图像近似服从周期性的抛物线分布的规律,首先采用两次矩阵变换,对噪声所在的坐标点进行锁定;继而利用掩模技术并结合二维离散余弦变换和Picard迭代方法,对噪声的传播进行抑制,从而获得平滑的图像。实验结果表明:激光散斑干涉测量对局部高密度噪声很敏感,经过平
