Abstract
The pulsed laser holographic vibration analysis on high-speed rotating structures presents several difficulties due to the rotational movement of the object between the two laser pulses recording the holographic interferogram: Apart from the vibrational motion the recorded holographic fringes can be additionally modulated due to the object's rotary motion. Beyond small angles of rotation, a decorrelation of the recorded object waves occurs, preventing the formation of high visibility interference fringes. To overcome these effects different holographic recording techniques can be used including an interferometer in which both the reference wave and the holographic recording plate are simultaneously rotating with respect to the object, and an interferometer in which an image derotator is incorporated. Conditions for the practical application are outlined, and examples of vibrational studies of high speed rotating components are presented.
