分析比较了数码相机和摄像机的特点和优势,利用数码相机的长焦距镜头、高像素、高灵敏度和彩色成像特性拍摄低照度谱线,获得了清晰的图样。介绍实验过程参数设置和调整要点、参数计算方法以及更高性能的同类设备。解决了背景干扰下的弱光数字化成像问题,减少了磁场电流变动以及实验设备的不确定因素,改进实验效果和提高实验质量。
This article compared the characters and advantages of digital cameras and cameras. It can take a clear picture of weaken spectrum , by auto colorful digital camera with high sensitivity , high pixels , and long distance focus lens. And the article introduced the parameters setting and key of adjustment in lab processing , parameters calculating methods , and other
higher performance equipments. The digital image of weaken spectrum in the background of the view is solved. The influence of magnetic current changes and the factors of errors are greatly reduced by decreasing the time of exposure. So the experiments are more effective and gotten a good quality.
