This paper int roduces fabrication of polystyrene and aluminum surface perturbation targets used for flank illumination Rayleigh2Taylor instability experiment . By figure transfer, incising targets, cont rolling constructional technique and measuring targets’ parameters, we obtained surface perturbation target s with sinusoidal surface perturbation figures with thickness of several tens micrometer, the wavelength about 50 micrometer and amplitude f rom several to several tens micrometer. The width of two kinds of eargets is about 200 micrometer and the profile is clear.
