利用传输矩阵法对相移光纤光栅的反射及透射谱进行了仿真，由于光栅的相移具有一般性，因此在本文中将光栅分为两部分，第一部分为未引进相移的均匀布拉格光栅，第二部分为引入了相移的均匀布拉格光栅(The transmission matrix method is used to simulate the reflection and transmission spectrum of phase shifting fiber Bragg grating. Because the phase shift of the grating is general, the grating is divided into two parts in this paper. The first part is the uniform Prague grating without the introduction of phase shift, and the second part is a homogeneous Prague grating with phase shift.)

帧间差分法是一种通过对视频图像序列中相邻两帧作差分运算来获得运动目标轮廓的方法，它可以很好地适用于存在多个运动目标和摄像机移动的情况。当监控场景中出现异常物体运动时，帧与帧之间会出现较为明显的差别，两帧相减，得到两帧图像亮度差的绝对值，判断它是否大于阈值来分析视频或图像序列的运动特性，确定图像序列中有无物体运动。图像序列逐帧的差分，相当于对图像序列进行了时域下的高通滤波。实例中有对应avi文件(Inter-frame difference method is a method that obtains the contour of moving object by differential operation of two adjacent frames in video image sequence. It can be well applied to the situation where there are multiple moving objects and camera moving. When abnormal object motion occurs in the monitoring scene, there will be obvious difference between the frame and the frame. By subtracting the two frames, the absolute value of the brightness difference between the two frames can be obtained. The motion characteristics of video or image sequence can be analyzed by judging whether it is larger than the threshold value, and whether there is object motion in the image sequence can be determined. The frame-by-frame difference of image sequence is equivalent to high-pass filtering of image sequence in time domain. There are corresponding avi files in the instance)
