摘　　要：采用高精度、低像差的光学分幅技术,结合高精度延时控制及超快门选通微通道板(MCP)轮替曝光技术,以及CCD图像采集方法,研制了高性能的超高速光电分幅相机,其摄影频率为2×108幅/秒,像面空间分辨率为36mm-1,可连续拍摄8幅1 600×1 200像素的大画幅图像。将该相机应用于钨丝发光实验和雷管破裂实验,获得了清晰的实验图像。We developed an ultra-high-speed electro-optical framing camera using high precision and low aberration optical subdivision, high precision delay,ultra-fast microchannel plate （MCP） exposure shutter and CCD image data acquisition system, with its performance indicators as the following, its image spatial resolution is 36 mm-1 ,its frame size is 1 600 × 1 200,and it can capture eight images with the photography frequency of 2 × 108 frame/s. Using this camera, we successfully obtained clear images of the luminescent process of the tungsten wire and the rupture process of the detonator.
