A laser Doppler vibrometer was created with the ability to measure the vibrations of distant objects up to 250 meters away. The vibrometer is provided with a scanning system for automatic vibration measurement in an array of points. The control program moves the probe beam according to the research protocol, processes and store information. To demonstrate the capabilities of the system, we studied of the amplitude distribution of vibrations and the distribution of longitudinal stresses in a cantilevered tube located at a distance of 22 meters. The measurements at different frequencies are in good agreement with the numerical calculations performed by finite element code CalculiX.Key words: -Pages of the article in the issue: 16-19Language of the article: Ukrainian
