Abstract
An optical technique is used to detect remotely structural vibrations when its natural frequencies are changed. The introduction of positive feedback causes the self-excited vibrations of the structure. The ins tallation efficiency was examined experimentally at a distance up to 5 00 m with a vibration amplitude of 0.1-5 mm. The scope for the optical determination of vibration parameters of real structures with a rough surface was analyzed.
