Assembly contains digital cameras with electro optical transducer, a powerful point light source, specific screen for receiving shadow pattern as well as image in reflected rays. The system allows investigator to obtain visual information on effects followed a super/hyper-sonic process under study and to perform measurements. To improve the quality of information in complex experiment is a basic problem for any investigator. Additional perfect visual information allows one to better understand the process under study, to carry out a simple education, to check numerical simulation, to perform accurate measurements, etc. The system is useful at performing the gasdynamics, aeroballistics, explosive experiments
