引言将摄象器件,更特殊一些是CCD阵列,与成象器件(如象增强器,条纹摄象管,示波器件)联结在一起的兴趣早在文献中描述过。这些混合器件的主要优点在于提供了图象记录、图象处理及扫描转换的可能性。摄象器件的优良特性及CCD器件在低噪声电平下处理微弱视频讯号的能力确保了这些优势。 INTRODUCTION The interest in linking image pickup devices, and more particularly CCD arrays, with imaging devices such as image intensifiers, video tube feeders, and oscillometric devices has long been described in the literature. The main advantage of these hybrid devices is the possibility of image recording, image processing and scan conversion. These advantages are guaranteed by the excellent features of the camera device and the ability of the CCD device to process faint video signals at low noise levels.
