The application of large anti-scatter grid is capable of remarkably decreasing scattered photons, whereas requires a very stable source position in order to reduce the loss of signal photons in the grid structure. The pinhole imaging technique is applied to observe spatial jitters of a triple-pulse radiographic source produced by a linear induction accelerator.
