普林斯顿(Princeton)科学仪器公司研制的SCCD-100型的CCD电视摄象系统,是为天文观察和其他需要非标准电视工作的其它科学应用而设计的.该系统中可将CCD(电荷耦合器件)冷却,以便将暗电流降低至某一水平,使得数小时曝光是可能做到的.视频信号以与数字计算机数据获取和最小噪声相适应的速率扫描输出.如图1功能方框图所示,该系统包括一个16位微处理器,使摄象系统有最大的灵 The SCCD-100 CCD television camera system, developed by Princeton Scientific Instruments, was designed for astronomical observation and other scientific applications that require non-standard television work in which a CCD (Charge Coupled Device) Cooling in order to reduce the dark current to a level such that a few hours of exposure is possible.The video signal is scanned at a rate appropriate for digital computer data acquisition and minimum noise.As shown in the functional block diagram of Figure 1, Including a 16-bit microprocessor, the camera system has the greatest spirit
