摘　　要：首次在国内研制了网格式高速摄影机,其技术性能是:网格版微透镜间距0.4mm,焦距1.6mm,面积100×125mm^2,像素数约8万个,摄影频率100～15×10~4F/s,总画幅数达300幅。文中论述了网格高速摄影的原理、设计和使用的问题,以及该机在网格版微透镜分辩率,电磁快门机构,微机控制和测速显示方面与国外同类产品相比较的先进性。This paper presents the principle, design and application of China's first high speed raster motion picture camera and the comparision between this camera and cameras of its kind in other countries. It is found that its resolution of the raster plate, the mechanism of electromagnetic shutter, the measurement of the frame rate, digital display and micro-computer control are superior to those of similar products made abroad.Specifications: distance between microlenses on the raster plate——0.4mm; focal length of the microlens——1.6mm; dimension of the raster plate——100×125mm^2; total pixels——80,000; range of frame frequency——1000～15×10~4 Frames/s; maximum frame number——300.
