Abstract. This paper presents the development of an experimental stand for the registration of time-averaged geometric circular moiré images. Optical interpretation of patterns of time‑averaged moiré fringes allows to identify the parameters of circularly vibrating structures. The developed scheme has a strong potential for designing experimental schemes capable to measure angular vibrations of rotating shafts in different mechanisms, and do not require any mountable sensors.

Keywords: geometric moiré, angular vibrations, time-averaged image.
