This paper describes and analyses the imaging performance of high speed raster photography with two dimensional pulse functional array. The lenticular plate has been used in the optical system to get the point-array-image of the raster plate which corresponds to the object. The density distribution of the point-array-image was measured. The resolution of the raster image is relative to the pitch of the raster plate. The high speed raster photography can obtain the higher relative brightness and lower resolution of image as compared with the conventional high speed photography. The frame interval is equal to the size of the image point. For conventional high speed photography^ a frame inteTyal must be larger than the height of frame. So "that raster photography can reach high framing rate. By reducing the frame size of ihe raster image, one can increase the resolution of the image.
