代码说明:

应用背景在杨氏双孔激光干涉实验中, 激光可被实验仪器分为频率相同相差恒定的两个相干波源 。这两个相干波源所发出的波又会在空间中发生干涉现象 ,在像屏上,显现出干涉的平面图像。下面就依据光干涉的原理 ,推导出杨氏双孔激光干涉实验所产生的三维干涉图像 ,以及部分二维干涉图像.关键技术  让激光束垂直射入双孔屏的两小孔之间 , 当激光穿过这两个离得很近小孔后随即发生衍射 ,在空间叠加后发生干涉 ,并在像屏上呈现出清晰的明暗相间的条纹。由于双孔发出的衍射波是两组同频率同相位的球面波 ,故在双孔屏的光射空间会发生干涉.

  • Kernel-ISOMAP
    Isomap is a manifold learning algorithm, which extends classical multidimensional scaling by considering approximate geodesic distance instead of Euclidean distance. The approximate geodesic distance matrix can be interpreted as a kernel matrix, which implies that Isomap can be solved by a kernel eigenvalue problem. However, the geodesic distance kernel matrix is not guaranteed to be positive semi-definite. A constant-adding method is employed, which leads to the Mercer kernel-based Isomap algorithm. Numerical experimental results with noisy. ‘Swiss roll’ data, confirm the validity and high performance of the kernel Isomap algorithm.
