Paper Abstract

Vibration modes of rotating objects generally show different vibration behaviour compared to modes of the stationary object. Several methods can be used for holographic vibration analysis of rotating objects: - Method with optimized holographic measuring arrangement - Method with optical image derotator - Method with laser triggering related to object location and phase of vibration - Method with holographic interferometer rotating synchronously to the object Optomechanical and optoelectronical devices developed to perform these methods as well as measurement results of vibration analysis on technical objects will be discussed.
