前言 1970年春,美国贝尔实验室W·S·波意耳和G·E·史密斯等人提出的电荷耦合器件(简称CCD)概念,已在1972年进入实际应用阶段。它是MOS结构的新颖器件,同时兼有存储功能和自扫描成象的特点,因此,引起了许多科技工作者的注意。目前已发展了多种结构的CCD,并获得了广泛的应用。本文概略地介绍了CCD的电荷存储与转移原理,着重分析了在微光下CCD的噪声对灵敏度和鉴别率的影响,以及CCD在微光下的应用。 Preface The spring of 1970, the United States Bell Labs WS Boyle and GM Smith and others proposed Charge Coupled Device (referred to as CCD) concept, has entered the practical application stage in 1972. It is a novel device of MOS structure, which has the characteristics of both storage function and self-scanning imaging. Therefore, it attracts the attention of many scientists and technologists. Has developed a variety of structures CCD, and has been widely used. In this paper, the charge storage and transfer theory of CCD is introduced briefly. The effect of CCD noise on the sensitivity and discrimination rate in low light and the application of CCD in low light are analyzed emphatically.
