This report presents some technical ways to solve the important problem of experimental gas dynamics – the development of a product range of systems designed to carry out optical and physi-cal research: shade and interference devices intended to get gas flows visualized in the wind tun-nels and ballistic paths within the operating field of dimensions of up to 1000 mm. In order to de-velop collimator objectives of 400-1000 mm in diameter and with the relative aperture of up to 1:2 for the optical and physical research systems, computer-generated hologram optical elements (CHOEs) of diffraction optics were used. Unique instruments have been developed and tested in the experiments.
