CHARGE-COUPLED DEVICES (CCD) AS IMAGE SENSORS

Tins is a general technical introduction to charge-coupled devices (CCD) used as image sensors and is most suitable for electronic engineers. Although a number of books on CCD are available at the present time, most of them have a large space dealing with its physics and manufacturing technology which is perhaps too much for electronic engineers but very often the electronics in them seems too little and quite old; therefore, this article is written to offer the basic technical information an electronic engineer should know if he or she is going to deal with a CCD subject.The content of this article is arranged as follows. The advantages of CCDs over vidicon tubes are described in chapter one; the main products of major manufacturers worldwide with basic specifications and simple explanation are listed in chapter two; chapter three and four deal with driving and analog circuit problems which are particularly related to CCDs; finally, the present and potential applications are given in chapter five. All the materials are intended to be very practical and many of them have been practised by the auther in his research work. It is believed that the readers will be able to begin their CCD work immediately after they finish reading this article.
