In the technical diagnostics and monitoring of high dynamic processes high-speed cameras are getting wider application. Recorded images sequence analysis of an object position makes possible to study also the oscillating movement. In this paper results of some exploratory research of test vibration signals are presented. The aim of the study was to examine the possibility of applying high-speed camera to vibration measurements in the frequency range up to 1000 Hz. The performed tests consisted in the simultaneous registration and analysis of vibration test signals using 4 alternative measuring systems. and then the determination of the frequency characteristics of vibration acceleration, total corrected (Wh characteristics) and uncorrected vibration acceleration values. The results of recorded image analyses of oscillating movement were compared with results of vibration acceleration measurements obtained using laser and piezoelectric transducers. Vibration acceleration spectra, the uncorrected and corrected (Wh characteristics) total vibration acceleration values were determined. Based on the achieved results, some limitations and conditions for the application of the high-speed camera used for vibration analyses have been identified. The test results confirmed the possibility of use of high-speed camera for research of low frequency vibration even at low displacements.
