Abstract
Theoretical and experimental aspects of frequency-bounded vibration investigations were observed. It was shown, that stroboscopic holography has an advantage in comparison with other ones. Digital calculation shows that the result depends on accuracy of setting the phases of stobe pulses. Thus, it is necessary to apply very precise driver for the creation of laser pulses in needed phases. Experimetnal set-up for stroboscopic holographic investigation of obunded vibration by using continue-wave laser was described. Experimental investigations have shown that stroboscopic technique allows to separate different mode-shapes vibrating simultaneously. Pulse laser and digital holographic technique was applied to frequency-bounded vibrational investigations as well. The results of digital evaluations of separated mode-shapes were presented.
