© 2019 Published under licence by IOP Publishing Ltd. The paper presents the diagnostic system for velocity measurements of reflecting objects in high energy physics experiments. The principle of continuous velocity measurements based on the Doppler frequency shift analysis of a probe monochromatic wave reflected by the moving surface of the sample. System is designed to measure velocity in the interval of 5-50 km/s. Powerful laser pulses expose the target and generate shock waves inside it. The back side of target is illuminated by probe laser beam at a wavelength of 660 nm. Scattered probe light collected by a lens and injected into the optical system. Two Mach-Zehnder interferometers with different reference delay etalons form a vernier measuring system. A passive channel records luminescence in the shock wave front. Spatial resolution of the optical layout is about 3 μm.
