积累型微光CCD摄像机是利用CCD变积累控制技术[2]而研制成功的一种高灵敏度摄像机．该成果所采用的技术路线是提出对微光图像信号进行积分，抑制随机噪声，利用CCD图像传感器具有的电荷积累特性，改变其读取转移时间，延长信号在CCD靶面上累积电荷的时间，从而提高静目标或亚静目标的灵敏度同时，研制了一系列抑制装置，从而有效地提高了信噪比 Accumulation of shimmering CCD camera is the use of CCD variable accumulation control technology [2] and successfully developed a highly sensitive camera. The technical route adopted in this achievement is to propose the integration of the low light signal, the suppression of random noise, the use of the CCD image sensor with the charge accumulation characteristics, to change the read transfer time, to extend the signal charge on the CCD target surface, Thereby increasing the static target or sub-static target sensitivity at the same time, developed a series of suppression devices, thus effectively improving the signal to noise ratio
