| 摘 要： | 围绕CCD(电荷耦合器件 )线阵在控制电路中的应用的难点 (如何将CCD输出的原始信号经过初步处理后所得的方波信号转换成直流电压信号 )进行了讨论和分析。首先介绍了两种传统的转换方法 ,并对这两种方法的优缺点进行了分析和比较。最后提出了一种新颖的转换方法 :基于滤波思想的方波 -直流电压信号的转换方法。经实验验证 ,这种方法所得的直流电压信号确实稳定、可靠

| Abstract: | The difficulty for applocation of CCD(charge coupled devices) in control circuit(how to transform square wave to direct voltage) is discussed and analyzed.Two kind of transformation methods are introduced at first and the advantages and disadvantages of the two kind methods are analyzed and compared too. A neoteric transformation method is brought forward at last:That is themethod of transforming square wave to direct voltage signal based on filter thought.The result of this method is stable and reliable through test and experiment. |
