摘要众所周知，人眼对于许多波段并不敏感，无法察觉到许多信息。人眼只能响应可见光波段的光，针对于这一弱点，人们逐渐开始着手开发各个波段的成像技术，以用来开拓人眼无法探测的领域。紫外探测就是近年来逐渐得以发展的成像检测技术之一。它是应用了紫外独有的“日盲效应”，即在200-280nm波段内几乎无法探测到来自阳光的能量这一原理，由此来探测被测目标发出或反射回来的紫外波段辐射，并再转化后处理。此项技术目前日益被关注并重视，得到了空前的发展。30062

结合现实生活中的需求，我们可能需要采集指纹信息等数据，如此便需要我们应用紫外探测扫描技术来采集可见光无法探测扫描到的指纹信息。而可见光波段的图像又具有分辨率高等优势。如何把两种图像融合起来，以达在同一张图像上可同时呈现两波段有用信息的目的，就是本文要着重讨论的问题。
本文首先叙述了相关的科研背景以及依据理论，概括了近代紫外探测领域的发展与成果。接着根据实际市场需求，研究并设计了紫外与可见的融合电路系统。依次介绍各部分的设计方案，其中包括各部分的运行原理、实现功能、选用器件等，其中系统主要核心部分使用的是TMS320DM642的DSP图像融合板，在此基础上搭建融合系统，以得到所需的紫外、可见融合图像。
得到所需的指纹图像后，可以直接显示，并且及时存储。最后对相关实验过程进行了描述和分析，并附上相关的实验数据及图片。

Title The UV and visible fusion system circuit design
Abstract
It is well known that the human eye is not sensitive to many band, is unable to detect a lot of information. Optical wavelengths of light, the human eye can only response to this weakness, people gradually started to develop each band imaging technology, to explore the human eye cannot detect areas. UV detection is one of gradually to the development of imaging detection technology in recent years. It is unique to the application of ultraviolet "blind effect", namely in 200-280nm band almost impossible to detect the energy from the sun this principle, the measured or reflected an opponent to detect ultraviolet radiation, and post-processing. And the technology is increasingly being attention, obtained the unprecedented development.
Combined with the requirements in real life, we may need to fingerprint information and other data, so then we need to use ultraviolet detection scanning techniques to gather visible light cannot scan the fingerprint information. And visible image has a resolution higher advantage. How to put the two kinds of image fusion, in order to reach on the same image, the purpose of useful information can be presented at the same time two band is discussed in this paper will focus on.
This paper first describes the related research background and on the basis of theory, summarizes the recent development and achievements in the field of UV detection. Then according to the actual market demand, research and the fusion of the ultraviolet and visible circuit system is designed. , in turn, introduces the design scheme of each part, including the principle, realize the function of each part, selection devices, etc, the system is the main core part used the TMS320DM642 DSP image fusion plate, on the basis of building integration system, in order to get the ultraviolet and visible image fusion.
After get the fingerprint image will be displayed, and stored in a timely manner. Finally, the related experimental process are described and analysis, and attach the relevant experimental data and pictures.
