摘　　要：视频面阵CCD相机已经得到了广泛的应用,为了解决不同的应用对高频率、高分辨率不同的要求等问题,同时扩大其应用范围,提出了一种适用于视频面阵CCD相机的多工作模式成像技术。首先,分析了视频面阵CCD的功能和特点,确定CCD的工作模式;其次,根据这些工作模式确定多模式成像的视频面阵CCD相机的组成;然后,详细阐述了时序驱动电路中工作模式的切换方法;最后,在各种工作模式下对视频面阵CCD相机分别进行了外场成像试验。实验结果表明:视频面阵CCD相机在各种工作模式下的成像效果很好,并且每种工作模式之间的切换时间为2ms,提高了视频面阵CCD相机多工作模式成像方法的有效性和实时性。To meet different requirements on high frequency and high resolution capacity in various applications,a kind of multi-pattern imaging technology using video area CCD camera was put forward.Firstly,the characteristics and functions of the video area CCD were analyzed to determine the working pattern of CCD.Secondly,the composition of the video area CCD camera with multi-pattern was determined according to these working patterns.Then the switching method of the working patterns in sequential driving circuit was elaborated in detail.Finally,outfield imaging tests were carried out on video area CCD camera under various working patterns.Test results show the video area CCD camera can obtain good imaging effect in various working patterns,and the switching time among different working patterns is 2 ms.The real-time and validity of the proposed imaging method are verified.
