摘　　要：本文针对应用于石油地质部门的荧光图象采集系统中被采集对象光强度弱这一特殊的应用环境 ,提出了一种用面阵CCD来实现线阵扫描方式的方法 ,避免了在以普通面阵采集方式采集任意长图象时所必须的图象拼接问题 ,同时通过从面阵CCD靶面抽取多列像元 ,经过移位叠加并作平均处理来改善由于荧光强度较弱导致采集得到的图象灰度对比偏低问题 ,增强了扫描得到的图象质量 ,满足了该应用的要求 ,提高了工作效率。In this paper, a method to realize the acquisitio n of the fluorescent image with the Plane-CCD in line-scan manner is proposed. In this way, the timeconsuming image splice operation which is strict with the original images but not almost so effective can be avoided, furthermore the qual ity of the acquired image is enhanced by extracting several lines of pixel on th e Plane-CCD and processing on it. The experiment result shows that the method is effective and can fulfill the application in the oil-field.
