The inconsistency of the spatial distribution of dynamic light pulse intensity introduced by hard-edged flux modulator and the way to overcome it are proposed. In theory, two-dimensional fast Fourier transform (FFT). Finally, the relation between the light transmittance of the system and the size of the beam focal spot and the width of the modulation slit is calculated. In order to show the complex pulse shaping capability of the system, the inertial confinement fusion (ICF) ) Complex laser pulse wave of interest.
