Paper Abstract

Holographic interferometry using a Q-switched double pulse ruby laser has been applied to study the out-of-plane vibrations of rotating objects. The elimination of fringe patterns due to the rotary motion of the object was achieved with a holographic interferometer in which the observation point coincides with a virtual position of the illumination point. In the second method described the rotary motion is optically removed with a reflective image derotator. Experimental results of the vibration analysis including standing and travelling waves of rotating disks, sawing blades and an automobile cooling fan with speeds up to 13.000 rpm are given.
