Fabrication and measurement of surface perturbation tiny targets in flank illumination experiment

This paper introduces fabrication of polystyrene and aluminum surface perturbation targets used for flank illumination Rayleigh-Taylor instability experiment. By figure transfer, incising targets, controlling constructional technique and measuring targets' parameters, we obtained surface perturbation targets with sinusoidal surface perturbation figures with thickness of several tens micrometer, the wavelength about 50 micrometer and amplitude from several to several tens micrometer. The width of two kinds of eargets is about 200 micrometer and the profile is clear.
