Abstract
A self-developed optical image derotator is applied for the analysis of the dynamic behaviour of rotating objects under operational conditions. This makes it possible to get a stationary image of the rotating object. Using the combination of image derotator and a high speed camera or a laser Doppler Vibrometer in-plane and out-of-plane vibration of rotating components with a rotational speed of up to n = 10.000 min-1 can be measured. The main component of this derotator is a rotating Dove prism. The prism causes aberration and polarisation effects that affect the measurement quality. To improve the optical and mechanical characteristics of the derotator and to expand its application potential, IMR develops a new derotator generation which uses an arrangement of mirrors instead of the Dove prism. Thereby it is additionally possible to do thermo-graphical measurements of the rotating machinery components. It is also possible to examine the objects with rotational speeds up to n = 20.000 min-1. In this paper the design and simulation of the optical module of the new derotator are introduced. Furthermore, the mechanical construction of the derotator will be explained.
