摘要:

为实现多应用环境下的高速摄像,提出一种面阵行间转移电荷耦合器件(CCD)多工作模式的设计方法。根据面阵CCD芯片KAI-0340D的工作原理,结合其内部结构特点和双通道数据传输方式,分析传感器的时序关系。改变不同区域的三电平和倾泻栅信号,由此实现4种分辨率成像。将各种工作模式分解为不同的场模式并存储在AD9979内部,通过改变场模式组合,实现在多种工作模式下运行。实验结果表明,该方法设计的时序可在4种分辨率下稳定工作,基本满足多种高速摄像的应用要求。

Abstract:

For the demand for multiple application environment of high-speed photography, this paper proposes a design method of area interline Charge Coupled Device(CCD) multiple working modes. After introducing the working principle of area CCD KAI-0340D, combining with the character of its internal structure and dual channel data transmission mode, the timing sequence of the sensor is analysed. The four resolution working modes are achieved by changing the three level signals and the FD signals in different regions. Different working modes are divided into different field modes and stored in AD9979. By changing the combination of different field modes in AD9979, the timing sequences of different working modes are realized. Experimental results show that the designed timing sequence of four kinds resolution works well, basically meet multi-application requirements for high-speed photography.

Key words: AD9979 signal processor, multiple working modes, high-speed photography, area Charge Coupled Device(CCD), field mode
