运用相关双取样(简称CDS)工作原理,可抑制CCD工作中产生的复位噪声.文中对CDS实验装置及实验结果进行了分析,对如何提高输出信号的信噪比进行了讨论.
By using the principle of correlated double sampling (referred to as CDS), it can restrain the resetting noise generated by CCD.The paper analyzes the CDS experimental device and the experimental results, and discusses how to improve the signal-to-noise ratio of the output signal.
