快递柜的开锁程序，采用 AT89S52单片机实现(The unlocking procedure of express cabinet adopts AT89S52)

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.)

本算法使用分治法求解最近点对问题。事先用O(nlogn)时间对x坐标进行排序，使得所有的点是按x坐标从小到大排好序的（x坐标相同时y坐标小的排前），然后取下标小于n/2属于左边的点集PL，取下标大于n/2属于右边的点集PR，即用O(1)时间就可以将规模为n的问题分解为两个规模为n/2的、同类型的子问题。分割完毕之后就可以采用分治法，分别求出PL和PR中的最近点对，最终通过递归实现。-This algorithm uses divide and conquer to solve the problem closest point. Prior to use O (nlogn) time to sort the x coordinate so that all points are based on x coordinates from small to large sorted (x coordinates with the same y coordinates of the small, the top), and then remove the standard is less than n/2 the set of points belonging to the left PL, remove the standard is greater than n/2 set of points belonging to the right of PR, that is to use O (1) time can be the problem size n divided into two size n/2, the same type The sub-problems. Segmentation can be used after completion of sub-rule method, respectively, find the PL and PR in the last points and eventually through the recursion.
