摘　　要：基于电子倍增电荷耦合器件(EMCCD,electronic multiplying CCD)的微光成像研究是当今的热点,在航天应用中有明显的优势和广泛的应用前景.EMCCD器件的电子倍增机制决定了其驱动具有高速高压的特点.由于对图像信息获取速率的要求越来越高,对驱动速度提出了更高的要求,然而目前超高速驱动仍是尚未完全解决的难题.总结了国内外EMCCD成像的研究进展,针对其存在的不足,提出了改良图腾柱、自耦态高频变压、集总参数电容串联谐振的驱动办法和宽范围精细调节、高效率、超低纹波具有可控上电初始态的电压转换方法,并给出了在实验方面的最新结果.最后对今后的研究工作进行了展望.Low light level imaging based on Electronic Multiplying CCD （EMCCD） is the focus of today＇s aerospace research, just as its obvious advantages and broad application prospects. The EMCCD＇s multiplying mechanism gives electronic multiplying driving high-speed and high-voltage characters. However, with the increasing demand for high speed image acquisition, the requirement of driving speed become higher, the superspeed driving mechanism become scientific problems that are not completely solved yet. The recent developments of the EMCCD imaging have been reviewed in this paper and new methods based on improved totem pole, EMCCD high voltage multiplying electrode＇s lumped parameters lumped capacitance series resonance, high frequency voltage autotransformation, and voltage transformation control model of EMCCD were proposed for the shortcomings of reported methods. Finally, the new experimental results have been reported and the future research prospects have been proposed.
