用于微光摄像的高灵敏度电子轰击电荷耦器件

文章综述微光成像的电子轰击电荷耦合器件（EBCCD）的进展。EBCCD是将像管的荧光屏以对电子灵敏的背照明、减薄CCD代替,将电子图像直接转变为视频信号,其在所有光照等级下,特别是在极低微光下的调制传递函数（MTF）、分辨力、信噪比、余辉等均优于像增强器耦合CCD（ICCD）。文中较为详细地叙述了倒像式EBCCD设计与减薄工艺,给出各种类型倒像式EBCCD像管的技术参数,分析和比较了近贴式与倒像式EBCCD与ICCD的性能,指出了EBCCD在军用夜视技术与民用技术未来发展中的地位与重要性。     

Detection of the Angular Distribution of the Signal Electrons in VLESEM

The topic of this work is the study of direct detection of electrons by Charge-Coupled-Devices (CCD). The aim is to design a detector for the angle and energy-selective detection of signal electrons in very low energy scanning electron microscopy (VLESEM), using an electron-bombarded CCD sensor (EBCCD). We concentrate upon two problems—the design of appropriate electronics and determination of an appropriate energy of the signal electrons for the CCD sensor.
