All-optical-microwave-filters
我们提出了一种新的方法来实现全光
微波使用光纤布拉格光栅阵列滤波
相同的反射率。确定了过滤器攻丝系数
通过一个宽带光源的光谱分布和
光栅的中心波长。由于光纤布拉格
光栅有相同的反射率，其特征
高均匀度的光栅是可能的，从而简化了
光纤布拉格光栅的制作，降低了实现
错误。此外，该宽带光的光谱分布
源可以控制使用的光学过滤器，可用于
控制滤波器系数的滤波器的旁瓣抑制。一个
微波滤波器采用四个光纤布拉格光栅的实验
实施。
(We propose a novel approach to realizing all-optical
microwave filtering using an array of fiber Bragg gratings with
identical reflectivities. The filter tapping coefficients are determined
by the spectrum profile of a broadband light source and
the central wavelengths of the gratings. Since the fiber Bragg
gratings have identical reflectivities, the characteristics of the
gratings with high uniformity are possible, which simplifies the
fiber Bragg grating fabrication and reduces the implementation
error. In addition, the spectrum profile of the broadband light
source can be controlled using an optical filter, which could be used
to control the filter coefficients to suppress the filter sidelobes. A
microwave filter using four fiber Bragg gratings is experimentally
implemented.)

信息熵
在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)
