摘　　要：针对高速摄影领域中采用外加辅助照明光源获取的图像效果欠佳、光源设备成本高以及在户外使用不便等问题,提出了基于像增强器的高速图像采集方法。该方法以9350EOS-3-PRO三代像增强器和MC1362高速相机为实验平台,设计了二者之间的接口转换模块使之能够很好的匹配连接,从光谱响应和亮度增益两个方面对图像采集系统进行实验和分析。验证结果表明,该方法在低照度环境下能显著提高成像效果,但在高照度环境下工作容易饱和,有待进一步改善。High speed photography of adding a auxiliary light source had the shortages of poor image quality, high light equipment costs and inconvenient outdoor use,a high speed image acquisition method based on image intensifier was put forward in this paper.Experiment had been done with this method based on the platform composed of 9350EOS-3-PRO third generation image intensifier and MC1362 high speed camera.The image in-tensifier interface converter module between them was designed so that it could match well.Analysis for the spectral response and luminance gain of the imaging system showed that the system could improve the image quality significantly in the low illumination,but likely to occur saturate in the high illumination and need further improvement.
