ABSTRACT:
A method and a device for measuring and mapping vibrations wherein one or a number of local sensors and a measuring means can make local registrations and frequency decompositions of the vibrations of an oscillating object. The same sensors and measuring means may be used in combination with an image-forming unit and an associated measuring means for local and image-forming recording of the vibrations of an oscillating object, respectively. By oscillating an excitation source an object can be made to oscillate harmonically. Furthermore, the local and image-forming measurements are collocated with the aid of a means for calculation.
