摘要

为了对月基极紫外相机输出的科学数据进行采集

将其生成图像并实时显示

设计了月基极紫外相机图像采集与实时显示系统。该系统选用XILINX公司的Virtex II系列FPGA作为图像采集和处理以及控制中心

完成科学数据接收、图像数据生成和存储以及USB接口控制功能

利用RS-422接口实现与极紫外相机的通讯功能

利用LVDS接口接收相机发送的科学数据。输出的图像数据通过USB总线传输到上位机

由上位机形成图像并实时显示。该系统与极紫外相机进行了联合成像实验

实验结果证明

本系统在光子计数率为66 kcps的情况下

能够正确地采集科学数据将其转换为图像数据并实现实时显示功能。

Abstract

In order to collect scientific data of lunar-based extreme ultraviolet camera

generate images

and display these images in real-time

a display system of lunar-based extreme ultraviolet camera is designed. This system adopts FPGA of XILINX Virtex II series as the image acquisition

processing and control core. It has the functions of receiving scientific data

generating and storing the image data

as well as controlling USB interface. The system can communicate with extreme ultraviolet camera based on RS-422 interface

and receive scientific data by LVDS interface. The image data is transmitted to computer through USB bus. And the computer can generate images and display these images in real-time. Imaging experiment

using this system and the extreme ultraviolet camera

has been done. The result of this experiment shows that the system can correctly collect scientific data

generate image data and display image when the photon counting rate is 66 kcps.
