一、引言在直接注入的红外CCD中,光生电荷是直接引入CCD移位寄存器的。因为这实际上是个直流耦合系统,而CCD处理电荷的容量有限,所以,只有直流电很小的探测器(即光伏本征探测器)可以与CCD耦合。直接注入红外CCD的关键参数是注入效率,它的定义是引入CCD的电荷与探测器产生的总电荷之比。本文证明,注入效率与频率 First, the introduction In the direct injection of infrared CCD, photogenerated charge is directly introduced CCD shift register. Since this is actually a DC-coupled system and the capacity of the CCD to process the charge is limited, only a detector with a very small direct current (ie a PV intrinsic detector) can be coupled with the CCD. The key parameter to inject the infrared CCD directly is the injection efficiency, which is defined as the ratio of the charge introduced into the CCD to the total charge produced by the detector. This paper demonstrates that injection efficiency and frequency
